Arquitectura Modular

To build a scalable Flutter app with modular architecture, organize the project into independent, reusable feature modules like auth and products using flutter_modular for routing and dependency injection.

flutter_modular handles dependency injection by managing routing and dependencies across distinct modules, while Melos manages the monorepo structure to allow concurrent development on separate packages with minimal conflicts.

The best way to manage multiple Flutter packages in a monorepo is using Melos, which allows different developers to work on separate feature modules concurrently within a single repository while enforcing clear dependency boundaries.

Independent Flutter modules communicate with each other using an event bus pattern, which facilitates interaction between components while maintaining single responsibility and enforcing unidirectional dependencies.

Yes, you can test individual Flutter modules in isolation, because the modular architecture enforces single responsibility and unidirectional dependencies, supporting dedicated testing strategies for each feature module without requiring the full application context.

You should split your Flutter app into separate feature modules when managing large applications becomes complex, allowing teams to break down features like authentication, cart, and payment into independent, reusable components.
