flutter-layer-based-clean-architecture

Structure a Flutter app with clean architecture by organizing code into domain, infrastructure, application, and presentation layers. Enforce inward dependencies so the domain layer remains pure and independent of Flutter or infrastructure details.

DTO to domain entity mapping happens in the infrastructure layer. This ensures the domain layer remains pure and strictly prevents DTOs from leaking into the presentation or application components.

Yes, you use get_it for inversion of control to inject repository implementations into BLoCs or Cubits. This maintains the inward dependency flow required by the clean architecture design.

Common anti-patterns include putting Material widgets in the domain layer, using DTOs in the UI, and placing Shared Preferences directly in repositories. These break the strict separation of concerns and inward dependency rules.

Layer-based clean architecture applies to both new and existing Flutter applications. It untangles dependencies by enforcing explicit data flow across domain, infrastructure, application, and presentation layers to improve scalability.
