I have a login screen with firebase phone authentication, I'm getting error " Unhandled Exception: type 'User' is not a subtype of type 'FirebaseUser' " when correct OTP is entered.
I have previously updated
AuthResult result = await _auth.signInWithCredential(credential); to UserCredential result = await _auth.signInWithCredential(credential);
Any help will be highly appreciated.
