Implement Clean Architecture in Flutter with distinct Presentation, Domain, and Data layers using Bloc or Riverpod for bulletproof state management.
These best practices will help you build solutions that are clean, performant, and intuitive for teammates to understand and scale.
Decoupling Domain from Framework APIs
Clean Architecture ensures that your mobile application's core business logic remains independent of UI widgets, database drivers, and third-party SDKs.
When Flutter introduces new widget primitives or when you swap network clients, your core use cases and entities remain completely untouched.
Do:Define repository contracts in Domain
Define abstract repository classes in the domain layer and implement them in the data layer using Dio or Supabase.
Avoid:Direct API calls inside StatefulWidget
Never instantiate HTTP clients or parse raw JSON directly inside build methods or widget controllers.
