Flutter for cross-platform mobile

Flutter app development services

We build cross-platform apps in Flutter: one codebase that ships to both iOS and Android, stays responsive on weak networks and survives being backgrounded mid-task. Typed, immutable state keeps it maintainable as it grows.

What's included

One codebase, every device

Maintaining separate iOS and Android apps means every feature is built twice and the platforms drift apart. Flutter lets one team own both from a single codebase, without the odd feel of a web view wrapped in an app. We build apps that look and behave native on each platform.

In scope
  • iOS and Android from a single Flutter codebase
  • Typed, predictable state management (Riverpod) and routing (go_router)
  • Offline-tolerant sync against your backend API
  • Native platform integration: camera, notifications, biometrics, deep links
  • Resilience to weak networks and being backgrounded mid-task
  • A release pipeline that ships both stores from one build
How we work

How we build Flutter apps

Typed state, generated models and a layered architecture keep the app maintainable as it grows, so a single team can own both platforms with confidence.

  1. 1

    Shape the app

    We pin down the flows, the offline behaviour, and the native integrations, and agree the architecture before building.

  2. 2

    Typed foundation

    State with Riverpod, navigation with go_router and immutable models with freezed: a foundation that scales past the first few screens.

  3. 3

    Build & integrate

    Screens and features in iterations, wired to your API with offline-tolerant sync and the platform integrations you need.

  4. 4

    Test on real devices

    Widget and integration tests, plus testing on actual hardware across the weak-network and backgrounding cases that break apps.

  5. 5

    Ship both stores

    A release pipeline that builds once and ships to both the App Store and Play Store, so features land everywhere at the same time.

Deliverables

What you receive

A production app on both stores, from one codebase your team can keep building on.

What you get
  • A single Flutter codebase running on iOS and Android
  • Typed state and routing with a clear, layered architecture
  • Offline-tolerant sync against your backend
  • The native integrations your app needs, done per platform
  • Widget and integration tests, run on real devices
  • A single-build release pipeline for both app stores

One Dart codebase for Android and iOS, typed and immutable state, and one team that owns both platforms. That is the foundation we build your app on.

Questions

Flutter development questions

Why Flutter instead of native iOS and Android?

Native gives you the best platform fidelity, but it means two codebases, two teams and every feature built twice. Flutter lets one team ship both platforms from a single codebase, so features land once and reach every device, without the web-view feel of older cross-platform tools. For most product apps the trade is worth it. If your app lives or dies on the newest platform APIs, we'll say so.

How does Flutter compare to React Native?

Both ship iOS and Android from one codebase. Flutter renders its own UI for consistent behaviour across platforms and versions, with strong typing via Dart; React Native leans on the JavaScript ecosystem and native components. We work in Flutter because typed state and a single rendering path keep large apps maintainable, but we'll recommend whichever fits your team and product.

Can you take over an existing Flutter app?

Yes. We start with a short review of the codebase (architecture, state management, test coverage and the riskiest areas), then either extend it or refactor the parts holding you back. You get a clear picture of what you have before we change anything.

Will the app handle bad networks gracefully?

That's a core focus. We build offline-tolerant sync so the app stays usable when the connection drops and reconciles cleanly when it returns. We also test the backgrounding and weak-network cases on real devices, because those are the situations that break apps tested only on fast office wifi.

Ship to both stores from one team.

Tell us about your app. We'll build it in Flutter from a single codebase, and it will feel native on both platforms.
