Why do we need to wrap a provider for FirebaseAuth.instance?

[amoslai5128]

Hi, I'm a starter of Riverpod and feel confused about the wrapping provider for instance. Therefore, I want to know why:

In your example:

// 1
final firebaseAuthProvider =
    Provider<FirebaseAuth>((ref) => FirebaseAuth.instance);

// 2
final authStateChangesProvider = StreamProvider<User>(
    (ref) => ref.watch(firebaseAuthProvider).authStateChanges());

What if?

// Directly use its singleton?
final authStateChangesProvider = StreamProvider<User>(
    (ref) => FirebaseAuth.instance.authStateChanges());

The purpose here is accessing FirebaseAuth with riverpod for easy testing. Otherwise how can we Mock FirebaseAuth ?
