Layered architecture organizes a Flutter codebase into UI, Logic, and Data layers with clear responsibilities. This separation of concerns keeps UI code simple, organizes business rules, and maintains data access.

Refactor by migrating toward cleaner feature boundaries using single-source-of-truth repositories and ViewModel-driven screens. This establishes unidirectional data flow and creates testable services for maintainable data access.

You need to separate UI, Logic, and Data boundaries when designing new apps, refactoring features, or migrating growing clients. This separation becomes necessary when maintaining scalable state management and organized business rules.

Yes, the architecture enforces unidirectional data flow by utilizing single-source-of-truth repositories and ViewModel-driven screens. This pattern ensures clear state separation and consistent data handling across the application.

Yes, clean architecture is applicable for client migrations that need UI, Logic, and Data boundaries. It helps transition growing apps toward cleaner feature boundaries, testable services, and repository-based data access.
