To structure a Flutter domain layer using Clean Architecture, define immutable Entities under lib/domain/entities and Repository Interfaces under lib/domain/interfaces to establish clear contracts between layers.

The best way to implement immutable entities in Flutter is by using the @immutable annotation alongside the copyWith method, while also overriding equality and hashCode for reliable state management.

Define repository interfaces in Flutter Clean Architecture by returning Future<Result<T>> with Entities rather than Models, ensuring the domain layer has no infrastructure dependencies.

You need a separate domain layer in your Flutter app when modeling a new business concept or defining a contract between layers, which provides a structured approach for scalable and testable applications.

When modeling Flutter domain objects, avoid anti-patterns like introducing infrastructure dependencies in repository interfaces or failing to use immutable Entities with copyWith, equality, and hashCode.

No, the Flutter domain layer requires zero infrastructure dependencies for repository interfaces, strictly utilizing Future<Result<T>> with Entities to maintain clean separation of concerns.
