Custom Flutter App Development
One app for Android and iOS, built in Dart with a clean architecture that’s easy to grow.
- Single Dart codebase
- Riverpod or Bloc state management
- Offline storage
- Unit, widget and integration tests
Launching on Android and iOS usually means two apps, two teams and two bills. With Flutter you get one codebase that ships to both stores, looks the same everywhere and is maintained by one team. As a Flutter app development agency in India, we build Flutter apps that feel native, with the backend, admin panel and store launch included.
A company that builds one app in Google’s Flutter framework that runs on both Android and iOS, then publishes and maintains it on Google Play and the App Store.
A complete Flutter product, not just screens: the app, the backend and admin panel behind it, the store launch, and full documentation at handover.
Flutter draws its own interface rather than borrowing each platform’s, which is why a Flutter app can look identical on an iPhone and a budget Android phone. The craft is in knowing where that helps, where a native touch is still needed, and how to structure the code so one team can keep both apps moving at the same pace.
From a first Flutter app to adding Flutter inside an app you already have, handled by one in-house team.
One app for Android and iOS, built in Dart with a clean architecture that’s easy to grow.
A custom design system that looks consistent on every phone, with platform touches where they matter.
The services behind your app, from Firebase for speed to a custom API for full control.
The integrations users expect, using trusted packages and native code where a package isn’t enough.
New screens or features built in Flutter and embedded inside your current native Android or iOS app.
Monthly care that keeps your app on a current Flutter version and compatible with new Android and iOS releases.
You want a custom, brand-led design that looks the same everywhere, you’re starting fresh, or you may also want web or desktop from the same code.
Your team already works in React or TypeScript, you want to share code with a React website, or over-the-air updates matter to you.
We build both Flutter and React Native, so the recommendation is about your project, not our preference.
In a free 30-minute call we’ll tell you honestly whether Flutter fits, and what both stores would take.
What Flutter is, who maintains it and why so many teams choose it for Android and iOS.
Google released Flutter 1.0, its first stable version, in December 2018. It’s been in active development and wide production use since.
Google, Flutter Live 2018Flutter apps are written in Dart, a language from Google that compiles to fast native code for release builds.
dart.devThe same Flutter codebase can target Android, iOS, web, Windows, macOS and Linux, though most business apps start with the two mobile stores.
flutter.devDevelopers see code changes in the running app almost instantly, which shortens design tweaks and review cycles.
flutter.devImpeller, Flutter’s newer rendering engine, is now the default on iOS and on modern Android devices, built for smoother animation.
Flutter release notesFlutter is open source under a BSD licence, so there’s no framework fee. You pay only for development, accounts and hosting.
github.com/flutterFlutter makes it easy to start an app. It takes experience to keep a Flutter app clean, fast and up to date two years later. That’s the part we’re good at.
A clear architecture, a proper state management pattern and carefully chosen packages, so your Flutter app stays easy to change long after launch, whoever maintains it.
Our team also builds native Android and iOS, so when a feature needs platform code, we write it ourselves.
Flutter’s rendering makes custom, brand-led design practical. We use it to make your app memorable.
Profiling with Flutter DevTools catches slow frames and memory issues before your users notice.
Flutter, Dart and package upgrades are scheduled, so the app never gets stuck on an old version.
As a flutter app development company headquartered in Noida, OGEN Infosystem works with startups and enterprises across India, with a lifetime usage licence and post-launch support from our flutter app development agency team.
Six steps from first conversation to live apps on both stores, each ending with something you can see and approve.
We confirm Flutter is the right fit, define the launch features, and note any device features that need native code.
You get: Feature listA Figma prototype you can tap through on Android and iPhone, with platform-specific touches where users expect them.
You get: Approved prototypeShort build cycles with test builds for both platforms every couple of weeks, while the backend and admin panel are built alongside.
You get: Builds for bothTesting on real Android phones and iPhones, with frame-rate and memory profiling so scrolling and animations stay smooth.
You get: Tested releaseWe prepare both store listings, handle Google’s and Apple’s review requirements, and release to both stores together.
You get: Live on both storesThe first month after launch is supported free. From then on, maintenance keeps Flutter, its packages and both platforms current.
You get: Stable appsFlutter makes a great first impression in a demo. The problems show up months later, and they almost always trace back to the same early decisions.
