Flutter explained

Flutter shines when iOS and Android are served from one shared codebase and the app needs a distinct design language that looks pixel-identical everywhere. Because UI and logic are shared, two separate native teams become unnecessary. A web build can be produced from the same codebase on top of that.

The interface is composed of widgets, with state managed separately from it – using Riverpod, BLoC or Cubit depending on project size. Platform-specific features Flutter doesn't cover are wired in through platform channels, with the necessary native code written in Swift or Kotlin. Kept cleanly apart, the shared code stays maintainable without giving up device capabilities.

Through REST or GraphQL APIs, like any other app. Authentication, deep links and analytics are covered by established packages, and existing native modules or SDKs are reached via platform channels. One special case is apps used without a stable connection: offline capability has to be part of the architecture from day one and is hard to retrofit.

Yes. Flutter can be embedded module by module into an existing native app, so nothing has to be rebuilt all at once. For React Native or WebView apps, though, the prior question is whether the switch is worth the effort – modernising what exists is often cheaper than changing frameworks.

If an app leans heavily on platform-specific native APIs or an SDK that only exists as an iOS or Android library, native development fits better. If your team lives in the React and TypeScript world, or the app should share logic with an existing web frontend, React Native is usually the more pragmatic route. For very lightweight applications a web app is often enough.

No. We build our cross-platform apps with React Native, because that is where our team is at home and app and web share the same TypeScript base. We follow and assess Flutter openly – this page is meant as decision support, not as a service offering. If your project clearly calls for Flutter, we will tell you so honestly.
