flutter-architecture

Applies the Flutter team's app architecture recommendations: UI and data layers, MVVM, repositories, unidirectional data flow, immutable models, dependency injection, navigation, naming and testing with fakes. Use when structuring a Flutter app or feature, deciding where logic belongs, reviewing widgets that hold logic, or planning tests per layer. Do not use for Dart naming and style (dart-code-standards) or for profiling and rebuild tuning.
