Structure Flutter apps with Clean Architecture by dividing code into Presentation, Domain, and Data layers. This enforces strict dependency rules and feature-based organization, ensuring scalable and maintainable project structures.

The best way to enforce dependency rules in Flutter is implementing unidirectional data flow between Presentation, Domain, and Data layers. This prevents common architectural violations by ensuring dependencies point strictly inward toward the domain.

Domain-driven design in Flutter works by organizing code into feature modules containing distinct Presentation, Domain, and Data layers. This isolates business logic into use cases and entities while keeping data sourcing separate.

You need Clean Architecture for your Flutter project when starting a new application or refactoring an existing one to establish a robust foundation. It promotes long-term code health and developer productivity in scalable applications.

Handle error handling strategies across Flutter architecture layers by defining clear responsibilities within the Presentation, Domain, and Data tiers. This approach manages failures systematically without violating unidirectional dependency rules.
