Undefined class 'AuthResult' in Flutter

Question

I have been trying to implement Google login screen using Flutter.

final AuthResult authResult = await _auth.signInWithCredential(credential);

The editor, for the line above, says:

Undefined class 'AuthResult'

How can I fix it? Any help would be very appreciated.

Have you imported it from the firebase auth? if so then close your IDE maybe that will help? — Tinus Jackson, Dec 17 '19 at 15:24

Starting from Version firebase_auth 0.18.0:

FirebaseUser has been changed to User

AuthResult has been changed to UserCredential

GoogleAuthProvider.getCredential() has been changed to GoogleAuthProvider.credential()

onAuthStateChanged which notifies about changes to the user's sign-in state was replaced with authStateChanges()

currentUser() which is a method to retrieve the currently logged in user, was replaced with the property currentUser and it no longer returns a Future<FirebaseUser>

The problem was firebase_auth version that I added to pubspec.yaml.

Previous version I have been using: firebase_auth: ^0.11.1+8

Now: firebase_auth: ^0.15.2

This change on versions has fixed the problem.

In 2020 firebase_Auth_version(0.18.3+1), they changed from AuthResult to UserCredential, and GetCredentials deprecated to credentials.
