Flutter app development cost is quoted per project and depends on features, platform mix, integrations, and backend complexity. We tailor the scope to fit your budget — whether you're shipping an MVP or a multi-country platform. Share your requirements on a short discovery call and we'll send a written estimate within 48 hours, free, with no obligation.
Most Flutter apps ship from kickoff to store launch in 8 to 16 weeks. An MVP across iOS and Android typically takes 8–10 weeks; mid-scope native-feel apps 12–14 weeks; apps spanning Flutter mobile, web, and desktop 14–20 weeks.
It depends on the team and the product. Flutter wins on rendering performance (Impeller), pixel-perfect consistency, and single-codebase breadth. React Native wins when your team is JavaScript-first and needs tight native UI adherence.
Yes. Flutter apps access every native iOS and Android API through platform channels, pigeon-generated type-safe bridges, or Dart FFI. Camera, BLE, biometrics, HealthKit, WidgetKit, HomeKit, background tasks — all supported.
Default is Riverpod for new apps. BLoC for larger teams with reactive patterns; Provider for small apps; GetX when the client's existing codebase already uses it.
Yes. Flutter apps are first-class citizens on both stores. We handle Privacy Manifests, App Tracking Transparency, Data Safety, and Play Integrity / App Attest.
Yes. We migrate React Native, Ionic, Xamarin, and Cordova apps to Flutter — usually screen by screen so the legacy app keeps shipping during the transition.
Default HTTP layer is Dio with Retrofit-generated clients and Freezed models. WebSockets or Firebase for real-time; Hive or Drift for offline. We also build backends in Python, Node, or Laravel.
Yes. Every engagement includes 90 days of post-launch monitoring with P1 fixes inside 72 hours, followed by an optional monthly retainer.
Yes. Flutter Web for dashboards and internal tools; Flutter Desktop for Windows, macOS, and Linux. For SEO-critical marketing sites, Next JS is usually a better choice.
TensorFlow Lite for on-device, Firebase Vertex AI for cloud LLMs, platform channels to Gemini Nano and Apple Intelligence, custom clients for OpenAI / Anthropic / Gemini.
You do. Full IP assignment is standard on invoice — source, CI/CD, design tokens, Figma files, and every plugin built for your project.
