I receive an error in flutter when creating a user sign in method using FirebaseAuth and FirebaseUser. Mainly telling me to either cast or change FirebaseUser to AuthResult both of which leads to a failure to create a firebase user resulting in No implementation found for method createUserWithEmailAndPassword on channel plugins.flutter.io/firebase_auth.
I have tried the responses from Android Studio without luck. The best fix is to revert to an earlier FirebaseAuth version. I'm currently using version: firebase_auth: 0.18.0+1.
when I write this line of code FirebaseUser user = await FirebaseAuth.instance.signInWithEmailAndPassword(email: _email, password: _password); itshow an error and 'FirebaseUser' is deprecated and shouldn't be used. Class Firestore is deprecated, use 'FirebaseFirestore' instead.. Try replacing the use of the deprecated member with the replacement.dartdeprecated_member_use And same withfirestore sdk dependencies firebase_core: 0.5.0 cloud_functions: 0.6.0 firebase_storage: 4.0.0 firebase_auth: 0.18.0+1
