Error while doing Firebase google sign_in

问题

I have implemented Google sign-in option in my project for users to sign in. The app is launching properly and I'm able to click on the google sign in, it is also displaying the google accounts available in my mobile but when I click on any account it is not moving to another page and throwing this error.

Here's my code:

final FirebaseAuth _firebaseAuth = FirebaseAuth.instance;
final GoogleSignIn _googleSignIn = new GoogleSignIn();

Future<FirebaseUser> _signIn(BuildContext context) async {

  Scaffold.of(context).showSnackBar(new SnackBar(
    content: new Text('Sign in'),
  ));

  final GoogleSignInAccount googleUser = await _googleSignIn.signIn();
  final GoogleSignInAuthentication googleAuth = await googleUser.authentication;

  final AuthCredential credential = GoogleAuthProvider.getCredential(
    accessToken: googleAuth.accessToken,
    idToken: googleAuth.idToken,
  );

  FirebaseUser userDetails = (await _firebaseAuth.signInWithCredential(credential)).user;
  ProviderDetails providerInfo = new ProviderDetails(userDetails.providerId);

  List<ProviderDetails> providerData = new List<ProviderDetails>();
  providerData.add(providerInfo);

  UserDetails details = new UserDetails(
    userDetails.providerId,
    userDetails.displayName,
    userDetails.photoUrl,
    userDetails.email,
    providerData,
  );
  Navigator.push(
    context,
    new MaterialPageRoute(
      builder: (context) => new Profile(detailsUser: details),
    ),
  );
  return userDetails;
}

Error:
