Flutter app architecture should use a feature-based project layout that clearly separates Services, Managers, and Views. This structure coordinates dependency injection, state management, and testable components across evolving codebases and teams.

Configure get_it dependency injection in Flutter by setting up a locator.dart file to register scoped services, managers, and proxies. This supports reproducible builds, safe service lifecycles, and robust testing guidelines.

ChangeNotifier and ValueNotifier managers drive reactive Flutter state by exposing async Commands for operations and lifecycle management. They coordinate with proxies wrapping DTOs to keep UI responsive with optimistic updates.

Use scoped services and DataRepository design patterns to manage user sessions and service lifecycles in Flutter. These patterns handle reference counting and ensure safe service disposal within your get_it dependency injection container.

Proxies in Flutter architecture wrap DTOs to add reactive behavior like computed properties and optimistic updates. You need them to keep UI responsive and encapsulate custom commands within feature-based modules.

This Flutter architecture pattern suits evolving codebases by enforcing consistent structure, reliable get_it dependency injection, and testing best practices. It ensures scalable feature-based modules with testable components across growing teams.
