Flutter app development services - iOS and Android from one Dart codebase that draws every pixel itself.
Intention InfoService builds cross-platform mobile apps with Flutter, for the products where the interface is the whole point. Flutter borrows nothing from the platform's widget set - its own engine draws the screen - which is why a custom, animation-rich design lands identically on both stores. That freedom is also a responsibility, and we engineer the parts it hands you: platform fidelity, accessibility semantics, motion, download size, native interop and the release pipeline. Published fixed prices, milestone billing, and you own the code, the IP and the store accounts. For startups, SMBs and enterprises worldwide.
Fixed price, paid by milestone, and we submit your app to both stores.

When the interface is the whole product
Flutter builds iOS and Android apps from a single Dart codebase, and unlike every other cross-platform toolkit it does not drive the platform's own widgets - its engine draws the screen. That is the reason to pick it: total control of the interface. It is one of our usual cross-platform choices, and a typical Flutter engagement is one of these:
Brand-led, animation-rich apps
The products where the interface is the whole point: a bespoke design language, custom motion, and screens that look and behave identically on both stores because nothing is left to a platform default.
New apps for iOS and Android
A product built once and shipped to both stores: navigation, state, auth, payments and the release pipeline, submitted to the App Store and Google Play for you.
MVPs and validation builds
A focused first version proven on real devices in real hands. Dart's hot reload makes design iteration genuinely fast, so the version you validate with is code you can keep building on.
Design systems and multi-brand apps
One widget library, themed per brand or per tenant. Because Flutter draws its own components rather than inheriting the platform's, a design system is enforced by the code instead of negotiated with the OS.
Apps on top of your backend
The Flutter client for an API you already run, or a new backend built alongside it - auth, data, business logic and integrations, designed together rather than negotiated across two vendors.
Rescue, audit and care
A Flutter app that feels a half-beat wrong, drags on mid-range devices, inherited a state architecture nobody understands, or is stuck on an old toolchain. We audit it and fix what actually hurts rather than rewriting by reflex.
Where Flutter ends, and where we'll send you
Flutter is a toolkit, not an answer to everything. When your question is really one of these, the answer lives somewhere else on this site:
Your web build has to be found on Google - Flutter on the web paints its interface onto a canvas instead of emitting semantic HTML, so it works against crawling, first paint and the accessibility tree. It is a fine choice behind a login, for an internal tool or a companion to a Flutter app. For anything that must rank, we route you to Next.js, when the web build has to be found on Google, and we say so before you spend.
Your team already writes JavaScript and TypeScript - Dart is a language most teams do not know yet, and that cost is real. If sharing logic with a React web codebase matters more than owning every pixel, consider React Native, the JavaScript route to the same two stores.
You haven't decided whether you even want an app - cross-platform, fully native or an install-free web app is a budget and strategy call before it is a technical one. That decision belongs on our mobile app development service, where we make that call with you in writing. And when the real work is the platform behind the app, that is the platform behind the app, scoped as custom software, with the backend and APIs your Flutter app calls built alongside it.
Is Flutter dead? Did Google abandon it? No - and the worry was fair.
This is the most-cited objection, and an honest answer starts by conceding the real part. In 2024 Google laid off staff across the Flutter and Dart teams, and later that year a respected former Flutter engineer launched Flock, a community fork, saying the remaining team was stretched thin and hard to reach. That frustration was genuine and it was reported openly, and anyone telling you it never happened is not worth trusting on the rest of the answer. Here is the part the "it's dead" posts leave out. Flutter kept shipping straight through it: its rendering engine reached stable and became the default, Dart kept advancing, stable releases have continued to land on a steady cadence, and Google still develops the project in the open - and ships Flutter inside some of its own products, per Flutter's own showcase. Because Flutter is open source under a permissive licence, its future does not hang on one team's headcount: the outside community is real, and the fork exists precisely as a backstop rather than a tombstone. Will it feel native? Yes, when it is built properly - Flutter draws real, platform-shaped interfaces, Cupertino patterns on iOS and Material on Android, and a well-built Flutter app is not something the person holding the phone picks out. Are Flutter apps bigger?They carry an engine, so there is a size floor a thin native app does not have. We engineer that down the documented ways and measure the real number on your build rather than quote you one. Flutter is not right for every product, and a few paragraphs below we tell you plainly when it isn't. But dead, it is not.
Why teams pick Flutter
It earns the job when owning the interface outright is the point - and it is the wrong answer often enough that we would rather tell you than sell you.
The interface is the whole product
Flutter draws every pixel with its own engine instead of driving the platform's widgets. A custom, animation-rich design renders identically on both stores and behaves exactly as it was drawn, because nothing is left to a platform default you cannot control.
One Dart codebase, two stores
You fund and maintain one product, not two. Features land on iOS and Android together, fixes ship once, and there is a single place to reason about behaviour rather than two implementations quietly drifting apart.
Compiled ahead of time to native code
In a release build, Dart is compiled ahead of time into native machine code for each platform. There is no JavaScript engine interpreting your app at runtime, which is a real architectural difference from the JavaScript-based cross-platform route.
Design iteration that actually moves
In development, Dart runs on a virtual machine with stateful hot reload, so a change to a screen appears in about the time it takes to look up. On an interface-led product, that loop is not a convenience - it is how the design gets good.
Open source, and not on one team's quarter
Flutter is open source under a permissive licence, developed in the open by Google with an active outside community, and since 2024 there has been a community fork standing by. Your leverage is not a promise from a vendor - it is a licence, public source, and code you own outright.
The same team can build the backend
Most apps are a thin client over a serious backend. Auth, APIs, data and integrations are work we do on the web every day, so the app and the server it talks to are designed together rather than handed between two vendors.
When we'd tell you not to use Flutter
Flutter earns the job when the interface is the whole product. It is not our reflex, and we won't pretend it is. On our React Native page we call React Native our default when a team already lives in React, and that still holds here: if your people write JavaScript and TypeScript, or you want an app that shares real logic with your web codebase and hires from a very large talent pool, we would rather send you there than push Dart on you. Dart is a language your team probably does not know yet, and that cost is real. When the product truly demands deep performance, hardware access or platform-specific behaviour from day one, fully native earns its higher price, and we would build it in going fully native on iOS with SwiftUI or native Android in Kotlin. And there is one place we will actively steer you off Flutter, on a site whose whole brand is search visibility: an SEO-critical web presence should not be a Flutter web build, because it draws to a canvas rather than emitting semantic HTML. That belongs in a search-indexable web app in Next.js, and we will say so before you spend. Whether it should be an app at all is the bigger call, and we make it with you in writing during discovery on our mobile app development service.
Twelve things the platform won't do for you
This grid is the argument of this page. When a toolkit draws its own pixels, nothing arrives correct by default - not the platform feel, not the accessibility semantics, not the motion, not the size. Each of these is a decision somebody has to make on purpose, and this is how we make them.
Impeller, and no first-run shader jank
Flutter's current rendering engine precompiles a small, fixed set of shaders when the engine is built, so a screen doesn't stutter the first time an effect appears. It doesn't make an app immune to jank, so we still profile motion on real, mid-range devices.
Dart, ahead-of-time compiled
A release build compiles your Dart, and the SDK's, into native machine code for each platform - no JavaScript engine interpreting at runtime. In development it runs on a virtual machine instead, which is what makes stateful hot reload possible.
Platform fidelity, and the gap we name
Material on Android, Cupertino patterns on iOS, adaptive layouts across screen sizes. Because Flutter draws its own widgets, when Apple ships a new design language Flutter's Cupertino set lags it until the framework catches up. Where a screen must match the newest OS look now, we bridge it with native platform views and tell you where the gap is up front.
Accessibility semantics, authored by hand
Flutter exposes a semantics tree to VoiceOver and TalkBack. Standard widgets emit it automatically, but anything custom-drawn must be given labels, roles and actions explicitly - so screen-reader support, dynamic text scaling, contrast, focus order and touch targets are build work we do and verify on real assistive tech, not defaults the OS grants.
Motion and gestures, engineered
Implicit and explicit animations, physics-based transitions and gestures that feel like the platform expects. Heavy work moves off the main isolate so the frame budget belongs to the interface, and we profile it on the mid-range hardware your users actually hold.
A state architecture you can inherit
Riverpod or Bloc chosen deliberately and used consistently, not three patterns fighting in one repository. The real cost of Flutter state management is inheriting somebody else's choice, so we document ours and keep it boring enough that the next team can read it.
Native interop when Dart runs out
Platform channels with type-safe bindings generated by Pigeon, and Dart FFI straight into C libraries. When a Flutter app needs real Swift or Kotlin - an SDK, a sensor, a legacy system - we write it, rather than working around it with something that breaks at the next OS release.
Download size, engineered and measured
Flutter ships its own engine, so a Flutter app has a size floor a thin native app doesn't, and we won't pretend otherwise. We bring it down the documented ways - tree shaking, split builds per architecture, deferred components, trimmed assets - and measure the real number on your build.
Widget, golden and integration tests
Widget tests for behaviour, golden tests to catch the pixel regressions that matter most when you draw every pixel yourself, and integration tests driven on real devices across the OS versions your audience actually runs.
Build, signing and store release
Reproducible builds, code signing, TestFlight and Play internal testing tracks, and submission to both stores. We build to each store's current review and testing requirements, which we confirm at kickoff, so a launch date is a real date.
Releases without a code-push escape hatch
Because Flutter compiles ahead of time, there is no sanctioned JavaScript-style over-the-air code push. Where it helps, Shorebird can patch Dart-level changes inside the store rules - never native code, plugins or assets, and never a way around review. So we keep what can safely change behind remote config and feature flags, and plan the release cadence honestly.
Backend, data and offline
Firebase, Supabase or the API you already run, with a local store, an explicit sync strategy and real conflict rules where the app genuinely has to work without a connection - and an honest conversation about which screens actually do.
Our default Flutter build:Dart with sound null safety and the modern language features - records, patterns, sealed classes - on Flutter's current rendering engine. One state-management choice, made deliberately and used consistently, because the expensive part of a Flutter codebase is never the widgets, it is the architecture the next team inherits. A design system expressed as a themed widget library rather than styling scattered across screens, since drawing your own pixels only pays off if the drawing is centralised. Platform fidelity treated as work: Cupertino patterns on iOS, Material on Android, and native platform views wherever the framework has not yet caught up with a new OS look. Accessibility semantics authored from the first screen and verified on real assistive technology, because nothing is inherited from the operating system. Heavy work off the main isolate, motion profiled on mid-range hardware, size trimmed the documented ways and measured on your build rather than promised as a number. Native code written by hand through platform channels or Dart FFI when the ecosystem stops. And we plan the release cadence around the fact that a real code change ships through store review rather than around it. Where we would not reach for Flutter is when your team already lives in React, when the product genuinely needs native from day one, or when the thing you are building has to be found by a search engine.
We won't pretend this page is a Flutter app.
It can't be one, and there isn't even a half-truth to dress up. This site is TypeScript and React rendering to the browser's DOM; Flutter is Dart, and its own engine draws every pixel. There is no Dart in this site's runtime, none in its build, none in its tooling, and not one Flutter-drawn pixel anywhere on it - and unlike our React Native page, there is not even a shared model to point at. We are a growing mobile practice and we have not shipped a Flutter app. So instead of a badge, here is the honest thing this page has that a mobile brochure never does.
Every pixel is ours to get right - and ours to get wrong
Most cross-platform pitches lean on the platform to do the hard part: drive the operating system's own buttons, lists and switches, and let iOS make it feel like iOS. Flutter does the opposite, and that is the entire reason to choose it. It borrows nothing from the platform's widget set - its own engine draws every pixel on the screen, the Cupertino switch and the Material ripple alike. Which is exactly why it earns the job when the interface is the whole product: nothing is left to a default you cannot control, so a custom, animation-rich design renders the same on both stores and behaves precisely the way it was drawn.
Here is the honest other half, and it is the standard we hold this page to. When you own every pixel, you own every mistake in one. There is no native control to inherit correct behaviour from, and no platform to blame when a screen feels a half-beat wrong. The accessibility semantics. Text fields, selection handles and text-editing behaviour. Scroll physics and overscroll. The contrast, the touch target, the gesture that has to feel right. The way each new version of iOS and Android restyles its own controls while your app keeps drawing the old ones. On Flutter every one of those is an engineering decision somebody makes on purpose, not a freebie the operating system hands you. Choosing Flutter is choosing to make craft a line item instead of a hope. Naming that precisely, and engineering each piece - which is what the twelve cards above are - is how you tell a team that takes the drawing seriously from one that assumes the framework will do it.
It will feel like the platform, because we draw it that way
Flutter doesn't wrap a web page in a shell - its own engine draws real, platform-shaped interfaces: Cupertino patterns on iOS, Material on Android, with the motion and gestures each platform expects. Because nothing is inherited from the OS, fidelity is our job rather than an accident. You work directly with the senior people making those calls, with no account-manager layer and no offshore hand-off, and we test on real, mid-range devices rather than the newest handset in the room.
Flutter's future doesn't ride on one team's quarter
Flutter is open source under a permissive licence, developed in the open, with an active outside community and, since 2024, a community fork standing by. But the thing that actually protects you is ownership rather than a promise: 100% of the code and IP transfers to you on final payment, written as standard, idiomatic Flutter, so you could hand it to any other Flutter team tomorrow with no licence back to us.
We engineer the download size, and measure it on your build
Flutter ships its own engine, so a Flutter app carries a size floor a thin native app doesn't, and we won't pretend otherwise. We bring it down the documented ways - tree shaking, split builds per architecture, deferred components, trimmed assets - and measure the real number on your build instead of quoting you one. That work is scoped in a short discovery, under an NDA on request, at a fixed price billed against approved milestones.
Dart is learnable, and you own everything, so you aren't locked to us
Dart is a small, conventional language a competent team picks up quickly, and we write standard, idiomatic Flutter that any Flutter developer can read - no in-house framework only we understand. You own the code and the IP outright, and the Apple Developer and Google Play accounts are registered in your name, so you can hire or move freely. Intention InfoService has been a registered company since 2016, and any care after launch is optional, with no lock-in.
Accessibility is build work, not a pre-launch scramble
Because Flutter draws its own pixels, screen-reader semantics, dynamic text scaling, contrast, focus order and touch-target size are things we implement and verify on real assistive technology, not behaviours the platform grants for free. So we treat them as work from the first screen. That is the accountability side of owning every pixel, and we would rather name it than quietly hope you never test it.
A code fix means a store release - and we plan for that
Flutter compiles ahead of time to native code, so there is no sanctioned JavaScript-style over-the-air code push, and we won't promise you a way to skip review. Where it helps, Dart-level patches can ship inside the store rules - never native code, plugins or assets. We plan the release cadence around that, keep what can safely change behind remote config and feature flags, and submit to both stores for you as part of the build.
We're honest about badges too - here are the exact ones we don't have
Flutter does run an official consultants directory on its own site, where firms apply through a Google form and the Flutter team reviews the submissions. We are not listed in it. Worth knowing, since agencies advertise this one: Flutter's own page is careful to say that being listed does not make a firm a Flutter or Google partner, and does not warrant the quality of their work - which is why we won't call it a partner programme either, and why you should treat an "official Google Flutter partner" badge with some suspicion. Google separately runs the Google Developer Experts programme, which has a Dart and Flutter category, but it recognises named individuals by referral rather than companies - a firm cannot be one, and nobody here holds it. "Flutter Favorite" is a different thing again: it is a designation the Flutter Ecosystem Committee gives to packages and plugins, usable only by that package's author, so it is not a company credential and we hold none. There is no Google Flutter or Dart developer certification - no Google exam, no professional credential - and the paid "certified Flutter developer" exams sold online are third-party products. The free Flutter courses Google itself publishes grant a certificate of completion, which is not the same thing and certifies no company at all. And the Apple Developer and Google Play accounts are not credentials: they are the paid memberships required to publish, which we register in your name and use to submit your app for you. What we offer instead of a badge is the depth on this page, published fixed prices, and code you own outright.
The craft Flutter lives on, we've shipped - on the web, in a different renderer, and we'll say so
Flutter earns its keep when the interface is the whole product, so the fair question is whether we can build interfaces. Here is the honest version of that proof. Our production work is real, custom web builds - a professional-training platform rebuild and a financial-services site, both on our work page - where the visual polish, the responsive layout, the motion and the accessibility all had to hold up in front of real users rather than in a mockup. That is the same discipline an interface-led Flutter build lives or dies on, and it is a skill that travels across renderers. What does not travel is the code, and we won't blur that line: every pixel of that work was drawn by the browser's DOM, not by Flutter's engine, and the page you are reading right now is a React and DOM interface too. So we will not hand you our own website as Flutter proof - a toolkit that draws its own pixels shares none of ours. See our work, honestly labelled, and never relabelled as a Flutter app, because none of it is one. The Flutter-specific proof on this page is the depth of what it knows about owning every pixel, and code you will own outright.
From one Dart codebase to both stores
We settle the design language before anyone builds a screen, and we'll tell you at the start if Flutter is the wrong tool for your product - so what launches is an app that passes review, feels right in the hand, and is still readable by the next team.
Discovery & tool fit-check
2-3 daysWe scope the app, the interface ambition behind it and the backend it needs, then agree a fixed price in writing - and if React Native or going fully native suits your product better, this is where we say so rather than after you've paid.
Design system & motion
1-2 weeksOn Flutter the interface is the product, so we settle the design language first: a themed widget library, the Material and Cupertino patterns each platform expects, motion rules, accessibility semantics and touch targets, decided before anyone builds a screen on top of them.
Build in Dart
weeksOne codebase, one deliberate state architecture, and platform fidelity treated as work rather than luck. Native code written by hand through platform channels or Dart FFI where the ecosystem stops. You see it running on a device each week, not in a slide.
Real-device QA & store submission
before launchWidget, golden and integration tests, then real, mid-range hardware across the OS versions your audience actually runs, with screen readers switched on. Signed, sent through TestFlight and Play internal testing, and submitted to both stores for you. We build to their current requirements, which we confirm at kickoff.
Hand over & care
OngoingThe repository, the code, the IP and the store accounts are yours. Optional care from $100/month covers monitoring, crash triage, OS-version updates and store compliance - and because a real code change ships through review rather than around it, we plan the release cadence with you.
The honest 2026 cross-platform toolkit comparison
We're stack-agnostic, so this is fair, not a pitch. These three take genuinely different bets on how an app gets drawn: Flutter renders everything itself, MAUI drives the platform's own controls from C#, and Ionic puts your web UI in a native shell. The bet is the decision.
| Flutter | .NET MAUI | Ionic / Capacitor | |
|---|---|---|---|
| Language | Dart | C# and .NET | JavaScript or TypeScript, HTML and CSS |
| How it renders | Its own engine draws every pixel | The platform's own native controls, from .NET | A webview - your web UI inside a native shell |
| How it's compiled | Dart, ahead-of-time compiled to native machine code | Compiled to native through .NET | Not compiled to native - it runs in the system webview |
| Best for | Highly custom, animation-rich interfaces | Teams already invested in C# and .NET | Content and simple apps a web team can ship fast |
| Look across platforms | Identical on both by default; matching each platform is your work | Adapts to each platform's own look | A web look, approximated on each platform |
| Our take | A strong pick when the interface is the whole product | The pragmatic route for a committed .NET shop | Fine for simple content apps, not a flagship |
In practice most Flutter decisions come down to Flutter or React Native, or Flutter versus going fully native - the two we build most. Weigh it against React Native, the JavaScript route to the same two stores, or against going fully native on iOS with SwiftUI and native Android in Kotlin. Kotlin Multiplatform is a different cross-platform model again, and .NET MAUI is Microsoft's successor to Xamarin. Whether you want an app at all - and whether it should be cross-platform, fully native or an install-free web app - is the bigger question, and it lives on our mobile app development service, where we make that call with you in writing.
What a Flutter app costs
No quote wall. These are our two published mobile app prices - the same numbers on our pricing page, on our mobile service page and in our schema. You see them before you commit, and you pay against delivered milestones, never all upfront.
Starter App
2-4 weeks
A simple, static or single-purpose iOS + Android app
- Cross-platform (React Native or Flutter)
- Up to a few screens, static or light content
- App Store & Play submission
- Info / content, no complex backend
Mobile App Build
8-14 weeks
SMBs and teams needing a full iOS + Android app
- Cross-platform (React Native / Flutter)
- App Store & Play submission
- Backend & APIs
- Real-device QA
How Flutter maps to the tiers - and what these tiers are not
On this page the cross-platform layer is Flutter. React Native still appears in the bullets above because we choose between the two per project and recommend the better fit in discovery, and we'd rather show you that than hide it. The Starter App from $500is a genuinely simple, single-purpose app - a few screens, static or light content, no complex backend. Please don't read it as the price of a full Flutter app, because it isn't. A real product-grade build - a design system, a backend and APIs, accessibility, real-device QA and both stores - is the Mobile App Build from $15,000. App Store and Google Play submission is included either way, and the store accounts are registered in your name. Sitting somewhere between the two, or validating an idea before you commit? Tell us the idea and your budget, and we'll scope one honest fixed price in a short discovery, in writing, before any build begins.

Flutter app development, answered
What is Flutter, and what is it used for?
Flutter is Google's open-source toolkit for building iOS and Android apps from a single codebase written in Dart. What makes it different from every other cross-platform option is that it does not drive the platform's own widgets - its own rendering engine draws every pixel on the screen. That is why it is chosen for products where the interface is the whole point: a custom, animation-rich design lands identically on both stores and behaves exactly as it was drawn. It is one of our usual cross-platform choices, alongside React Native.
Is Flutter dead? Did Google abandon it?
No, though the worry was fair. In 2024 Google laid off staff across the Flutter and Dart teams, and later that year a former Flutter engineer launched Flock, a community fork, saying the remaining team was stretched thin. That frustration was real and openly reported. What the 'it's dead' posts leave out is that Flutter kept shipping through it: its rendering engine reached stable and became the default, Dart kept advancing, stable releases continue to land on a steady cadence, and Google develops the project in the open and ships Flutter inside some of its own products. Because Flutter is open source under a permissive licence, with an active outside community and a fork standing by, its future does not hang on one team's headcount.
Flutter or React Native - which should I choose?
Both are excellent, and we build both, chosen per project. Flutter is the pick when the interface is the whole product - a custom, animation-rich design where owning every pixel is the point, because its own engine draws the screen rather than driving the platform's components. React Native fits teams already in the JavaScript and React ecosystem, shares logic with your web codebase, and hires from a very large talent pool. Neither is universally faster or better. On our React Native page we call React Native our default when a team or product already lives in React, and that still holds. In discovery we recommend the one that fits your product, your team and your budget, in writing, before any build.
Why Dart, and not JavaScript?
Because Flutter needed a language it could compile two different ways. In a release build, Dart is compiled ahead of time into native machine code for each platform, so there is no JavaScript engine interpreting your app at runtime. In development, the same code runs on a virtual machine, which is what makes stateful hot reload possible - you change a screen and see it in about the time it takes to look up. Dart is also small and conventional: if your team writes TypeScript, Java, Swift or Kotlin, the syntax will feel familiar within days.
Nobody on my team knows Dart - does that lock me into your agency?
No, and it is a fair thing to worry about. Dart is a small, conventional language a competent team picks up quickly, and we write standard, idiomatic Flutter that any Flutter developer can read - no in-house framework only we understand, and one state-management choice used consistently rather than three patterns fighting in the same repository. You own the code and the IP outright, and the Apple Developer and Google Play accounts are registered in your name, so you can hire or hand the project to another team without asking our permission. If Dart is a cost you would rather not pay at all, that is a real argument for React Native, and we will say so.
Will a Flutter app feel native?
Yes, when it is built properly - but it is earned rather than inherited. Flutter draws real, platform-shaped interfaces: Cupertino patterns on iOS, Material on Android, with the motion and gestures each platform expects. Because nothing comes from the operating system for free, the things a native control would give you automatically - scroll physics, text selection behaviour, focus order, the newest platform styling - are engineering decisions somebody has to make on purpose. Apps feel wrong when nobody made them. We build to platform patterns and test on real, mid-range devices rather than only the newest handset.
Are Flutter apps bigger to download?
Yes, and we would rather say so than dodge it. A Flutter app ships its own rendering engine, so it carries a size floor a thin native app does not have. We bring it down the documented ways - tree shaking, split builds per architecture, deferred components, trimmed assets - and we measure the real number on your build rather than quote you one for an app that does not exist yet. For most products the size is a non-issue; if your audience is on constrained devices or expensive data, that is a genuine input into whether Flutter is the right call.
What is Impeller?
Impeller is Flutter's current rendering engine, and it is the clearest signal that a Flutter codebase is modern rather than dated. Its main contribution is predictability: it precompiles a small, fixed set of shaders when the engine is built, so a screen no longer stutters the first time a particular effect appears. It is not a cure for every stutter - layout work, heavy computation on the main isolate and badly built lists still cause jank - so we still profile motion on real, mid-range hardware rather than assume the engine has handled it.
Is a Flutter app accessible to screen-reader users?
It can be, and it is build work rather than a default. Flutter exposes a semantics tree that VoiceOver and TalkBack read. Standard widgets emit that automatically, but anything custom-drawn - and on an interface-led Flutter app, a lot is custom-drawn - has to be given labels, roles and actions explicitly. So screen-reader semantics, dynamic text scaling, contrast, focus order and touch-target size are things we implement from the first screen and verify with the assistive technology switched on. This is the accountability side of a toolkit that draws its own pixels, and any agency telling you accessibility comes free on Flutter has not shipped one.
Can you push a fix without an app-store release?
Not the way you can with JavaScript-based frameworks, and we will not pretend otherwise. Flutter compiles ahead of time to native machine code, so there is no sanctioned JavaScript-style over-the-air code push. Where it helps, Dart-level patches can be delivered inside the store rules - never native code, plugins or bundled assets, and never as a way around review. So we design for it: whatever can safely change stays behind remote config and feature flags, and we plan a realistic release cadence with you rather than promise a hotfix path that does not exist.
Can a Flutter app be rejected by the App Store?
Apple can reject any app, and being built with Flutter is not a reason it would. Apps are judged on experience and policy, not on which toolkit drew them, and Flutter apps ship in both stores every day. Rejections happen for the same reasons they happen to fully native apps: broken flows, missing privacy disclosures, unclear permission use, thin functionality, or a mismatch between what the listing promises and what the app does. We build to each store's current review and testing requirements, which we confirm at kickoff, and we submit your app for you.
Is Flutter good for the web, and for SEO?
For SEO, no - and we say that on a site whose whole brand is search visibility. Flutter on the web paints its interface onto a canvas rather than emitting semantic HTML, so it works against crawling, first paint and the accessibility tree. It is a separate target from your mobile app, not a free extra. Where Flutter web genuinely earns its place is behind a login: an internal tool, an authenticated dashboard, or a companion to a Flutter mobile app where the code sharing is worth it. If the thing has to rank on Google, we will route you to a Next.js build and tell you so before you spend.
How much does a Flutter app cost?
We publish the numbers, and the honest driver of the price is the interface ambition rather than the language. A Flutter app is priced on our two mobile tiers: the Starter App from $500 for a genuinely simple, single-purpose app of a few screens with static or light content and no complex backend, and the Mobile App Build from $15,000 for a full product with a design system, a backend and APIs, real-device QA, and submission to both stores. The $500 tier is not a full app and we will not sell it as one. If your project sits between the two, we scope one fixed price in a short paid discovery, in writing, before any build.
How long does it take to build a Flutter app?
A Starter App is typically 2 to 4 weeks and a full Mobile App Build is typically 8 to 14 weeks. On Flutter the variable is rarely the code - it is the interface. Because nothing is inherited from the platform, the design system, the motion, the accessibility semantics and the platform-fidelity work are real line items rather than things the operating system hands you, and store review is something we plan around rather than promise a date for. We settle the design language before anyone builds screens on top of it, and we agree a fixed price before the build.
Are you a Flutter Partner, or certified?
No, and we will not imply otherwise. Flutter runs an official consultants directory on its own site, where firms apply through a Google form and the Flutter team reviews submissions. We are not listed in it. Worth knowing: Flutter's own page states that being listed does not make a firm a Flutter or Google partner and does not warrant the quality of their work, so an 'official Google Flutter partner' badge is describing something that does not exist. Google Developer Expert is a separate programme with a Dart and Flutter category, but it recognises named individuals by referral - a company cannot be one, and nobody here holds it. 'Flutter Favorite' is awarded by the Flutter Ecosystem Committee to packages and plugins, usable only by the package author, so it is not a company credential. And there is no Google Flutter or Dart developer certification: no exam, no professional credential. The free Flutter courses Google publishes grant a certificate of completion, which certifies no company at all, and the paid 'certified Flutter developer' exams sold online are third-party products.
Is this website built with Flutter?
No. Flutter draws its own pixels with its own engine and targets iOS and Android. This site is a TypeScript and React build that renders to the browser's DOM - there is no Dart in its runtime, none in its build, none in its tooling, and not one Flutter-drawn pixel on it. Unlike our React Native page, there is not even a shared model to point at. We are a growing mobile practice and we have not shipped a Flutter app, and we will not hand you our own website as Flutter proof. What we can point to is real interface craft shipped in production on the web, and the depth on this page about what owning every pixel actually obligates a team to do.
