Unable to use CopyWith when models are imported with namespace

[rbresjer]

Describe the issue

I make use of FlutterFire Firebase Authentication. This package declares a model User which clashes with my own User model. Therefore I import Firebase Authentication namespaced: import 'package:firebase_auth/firebase_auth.dart' as firebase_auth;. I have a model AuthenticationState which looks as follows:

@CopyWith()
class AuthenticationState {
  AuthenticationState({
    required this.user,
    this.firebaseUser,
  });

  final User user;
  final firebase_auth.User? firebaseUser;
}

CopyWith however doesn't take the namespace in account and sees both properties as User. I also tried defining a typedef typedef FirebaseUser = firebase_auth.User; and use that, but CopyWith then still types firebaseUser as User which resolves to my own User model.

Seeing a similar thing happen with a field that has been typedefed to another (imported) class. It seems to not use the typedef name, and also doesn't import the underlying source file.

This is also causing problems for me, since I have a class that uses two libraries that have classes with the same name, so obviously i have to import as at least one of them, but since this extension doesn't recognise namespaced imports, it fails.
