Error after logging in Google Account[flutter][ google_sign_in]

Issue

I noticed such a problem that sometimes don't log in to Google account. In the release or debug build, the auth works, but this error often pops up. This problem did not exist before with the same configuration.

I/flutter (16382): [firebase_auth/invalid-credential] The supplied auth credential is malformed or has expired. [ Invalid Idp Response: access_token
audience is not for this project ]
E/flutter (16382): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: NoSuchMethodError: The getter 'user' was called on null.

Code:

final FirebaseAuth _auth = FirebaseAuth.instance;

Future<String> signInWithGoogle() async {
  // Trigger the authentication flow
  final GoogleSignInAccount googleSignInUser = await GoogleSignIn().signIn();

  // Obtain the auth details from the request
  final GoogleSignInAuthentication googleAuth =
      await googleSignInUser.authentication;

  // Create a new credential
  final AuthCredential credential = GoogleAuthProvider.credential(
    accessToken: googleAuth.accessToken,
    idToken: googleAuth.idToken,
  );

  UserCredential authResult;
  try {
    // Attempt to sign in the user in with Google
    authResult = await _auth.signInWithCredential(credential);
  } on FirebaseAuthException catch (e) {
    print(e);
  }

  final User user = authResult.user;

  assert(user.email != null);
  assert(user.displayName != null);
  assert(user.photoURL != null);

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

  final User currentUser = _auth.currentUser;
  assert(user.uid == currentUser.uid);

  final DatabaseServiceUser db = DatabaseServiceUser();
  await db.createUser(currentUser);

  return 'signInWithGoogle succeeded: $user';
}

Solution

The error turned out to be on Google's side. After creating a new project in firebase, everything worked successfully with the same configuration as in the past.
