Dart, Riverpod, platform channels written in Swift and Kotlin. Pixel-perfect parity across iOS and Android. We treat Flutter as a serious engineering platform — not a faster way to ship sloppy code.
What kind of Flutter work this is
Most of our Flutter engagements are: MVP-stage launches needing to be in both stores in 10–14 weeks; mature apps approaching 100K+ MAU needing careful state-management refactors; multimedia apps where Flutter’s rendering pipeline genuinely beats React Native’s bridge; cross-platform apps for clients whose web codebase is already React but who want native feel on mobile.
We won’t recommend Flutter when iOS or Android native is genuinely the right call — deep system integration (HealthKit, ARKit, advanced biometrics, complex CarPlay), apps competing for App Store featured placement, or apps with performance characteristics that require native rendering paths. We’d rather route you to iOS native or Android native.
What we build
State management
Riverpod or Bloc, depending on team preference and project scale. AsyncNotifier for data fetching, StateNotifier for local state. We avoid setState beyond the simplest of widgets — it scales badly and reads worse a year later.
Navigation
go_router for type-safe declarative routing. Deep links wired from day one (not as a phase-two retrofit). Universal Links / App Links for App Store / Play Store deep-link entry. Web routing where the project also targets Flutter for Web.
Backend / data
REST or GraphQL via Dio plus Retrofit or graphql_flutter. Local persistence via Drift (SQLite) or Isar for offline-first apps. Firebase or Supabase when BaaS is genuinely the right choice; custom Node or .NET backends when it isn’t.
Native channels
Platform-channel work in Swift and Kotlin for the native APIs Flutter doesn’t expose — biometrics, payment SDKs, AR, Bluetooth LE, advanced camera, HealthKit lite. The Swift / Kotlin is written by the same team that writes the Dart, not handed off to a different vendor.
Distribution
App Store Connect plus Google Play Console operated end-to-end. Internal testing tracks, TestFlight beta cycles, Firebase App Distribution for stakeholder previews. CI/CD via Codemagic, Bitrise, or GitHub Actions with macOS runners for iOS builds.
Where Flutter genuinely earns the choice
- D2C consumer apps that need to be in both stores fast with pixel-identical UI
- Internal tools that field staff use across mixed iOS / Android device fleets
- MVP-stage products validating market fit before committing to native rebuilds
- Apps with shared design language across web, mobile, and (occasionally) desktop
- Multimedia / canvas-heavy apps where Flutter’s Skia/Impeller rendering wins over React Native’s bridge model
Pricing
- MVP Flutter app (single happy-path, auth, 1–2 feature areas): $35K–$80K, 10–14 weeks
- Full v1.0 cross-platform app: $80K–$200K, 16–28 weeks
- Refactor of existing Flutter app (state management, performance, navigation rewrite): $25K–$90K, 6–14 weeks
- Native channel module work (added to an existing app): $8K–$30K per module
