flutter-architecture

To structure a Flutter app using feature-first organization, group code into business feature modules under a features/ directory, such as todos/, with each module containing its own presentation, viewmodel, and data layers for scalability.

The best way to separate UI and business logic in Flutter is applying the MVVM pattern. It isolates Views in the UI layer from ViewModels in the domain layer, ensuring scalable architecture and maintainable code across complex application features.

Clean architecture applies to Flutter development by dividing the project into UI, Domain, and Data layers. This structure enforces separation of concerns, guides data flow, and establishes scalable patterns for large multi-feature applications.

Yes, you can use MVVM with clean architecture layers to build a scalable Flutter app. The pattern maps ViewModels to the Domain layer and Views to the UI layer, aligning perfectly with feature-first modules for 5+ features.

You need a feature-first project structure in Flutter when architecting apps with 5+ features and shared UI components. It groups code by business capability, preventing tangled dependencies and improving team collaboration across modules.
