Clean Mobile Architecture in Flutter with Riverpod 2.0
How to structure Flutter apps with decoupled domain layers, testable AsyncNotifier providers, and zero memory leaks.
# Structuring Flutter Applications
Scaling mobile codebases requires keeping state lifecycle management separate from presentation widgets.
The Three-Layer Pattern
1. **Domain Layer**: Pure business logic and entities with no framework dependencies. 2. **Data Layer**: API clients and local SQLite database cache repositories. 3. **Presentation Layer**: Stateless widgets reacting to Riverpod providers.
This layout keeps code testable, avoids widget rebuild cascades, and hits a consistent 60 FPS across iOS and Android.
