Flutter Phone authentication error original example

It looks like that sample is outdated , you can omit AuthCredential and GoogleAuthProvider.

    Future<String> _testSignInWithGoogle() async {
        final GoogleSignInAccount googleUser = await _googleSignIn.signIn();
        final GoogleSignInAuthentication googleAuth =
        await googleUser.authentication;

        final FirebaseUser user =
            await FirebaseAuth.instance.signInWithGoogle(
          accessToken: googleAuth.accessToken,
          idToken: googleAuth.idToken,
        );

        assert(user.email != null);
        assert(user.displayName != null);
        assert(!user.isAnonymous);
        assert(await user.getIdToken() != null);

        final FirebaseUser currentUser = await _auth.currentUser();
        assert(user.uid == currentUser.uid);

        return 'signInWithGoogle succeeded: $user';
      }

    Dears,

    I am developing this example (the original) of phone authentication: https://github.com/flutter/plugins/tree/master/packages/firebase_auth/example

    Of course, I added the .json and correct dependencies (I think, because other complements of firebase works fine).

    But, I get this part of code:

    Future<String> _testSignInWithGoogle() async {
        final GoogleSignInAccount googleUser = await _googleSignIn.signIn();
        final GoogleSignInAuthentication googleAuth =
        await googleUser.authentication;
        final AuthCredential credential = GoogleAuthProvider.getCredential(
          accessToken: googleAuth.accessToken,
          idToken: googleAuth.idToken,
        );
        final FirebaseUser user = await _auth.signInWithCredential(credential);
        assert(user.email != null);
        assert(user.displayName != null);
        assert(!user.isAnonymous);
        assert(await user.getIdToken() != null);
    
        final FirebaseUser currentUser = await _auth.currentUser();
        assert(user.uid == currentUser.uid);
    
        return 'signInWithGoogle succeeded: $user';
      }
    

    I have theses errors:

    • Undefined AuthCredential
    • Undefined name GoogleAuthProvider
    • The method signInWithCredential is not defined for class FirebaseAuth

    Can you help me please? I don't understand these error if it is the original example.

    Thanks!!
