Flutter layered architecture separates presentation, business logic, and data access into distinct layers. Organize code into UI, Logic, and Data components with clear responsibilities to improve scalability and ensure testable application design.

Implement MVVM and repository patterns by structuring Dart code into Views, ViewModels, Services, and Repositories. This separates data access from business logic, improving testability and maintaining clear component responsibilities across features.

Refactor Flutter projects by reorganizing code into UI, Logic, and Data layers. Define responsibilities for each component, apply dependency injection, and use ViewModels and Repositories to untangle presentation from business logic.

Yes, dependency injection supports feature development workflows in Flutter. Guide implementation from domain modeling through validation by injecting services and repositories into ViewModels, ensuring components remain testable and decoupled.

Apply MVVM and repository patterns when your Flutter app requires scalable architecture and high testability. Choose layered separation over simpler structures to prevent tangled code as data access and business logic complexity grows.
