To wire Firebase services behind clean interfaces in Flutter, define domain-level interfaces and wrap the Firebase SDKs in concrete data implementations. Use a GetIt-based bootstrap at the composition root to inject these dependencies, decoupling business logic from Firebase SDKs.

Mock Firebase Analytics and Crashlytics in Flutter tests by replacing concrete data implementations with fake stubs. The layered architecture uses domain interfaces that can be easily swapped during testing, ensuring your business logic remains decoupled from Firebase SDKs.

Manage dev and prod Firebase flavor configurations by providing flavor-specific setup files and wiring them into your GetIt bootstrap. This allows your Flutter app to load the correct Firebase configurations dynamically without altering the domain interfaces or business logic.

Yes, you can use dependency injection with Remote Config and App Check in Flutter. Register domain interfaces for these services and map them to their concrete Firebase implementations using GetIt, enabling test-friendly replacements and clean architecture.

Decoupling Firebase SDKs from business logic in Flutter ensures testability and clean architecture. By enforcing domain interfaces and concrete data implementations, you can swap or stub Firebase services during testing without modifying the core application logic.
