`import 'dart:async'; import 'dart:convert' show json;

import 'package:googleapis_auth/auth_io.dart'; import "package:http/http.dart" as http;

import 'package:firebase_auth/firebase_auth.dart'; import 'package:google_sign_in/google_sign_in.dart'; import 'package:googleapis_auth/auth.dart';

final FirebaseAuth auth = FirebaseAuth.instance; GoogleSignIn googleSignIn = GoogleSignIn( scopes: scopes, );

Future login() async { final GoogleSignInAccount googleSignInAccount = await googleSignIn.signIn(); final GoogleSignInAuthentication googleSignInAuthentication = await googleSignInAccount.authentication;

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

// You'll need this token to call the Youtube API. It expires every 30 minutes.
final token = googleSignInAuthentication.accessToken;

final AuthResult authResult = await auth.signInWithCredential(credential);
final FirebaseUser user = authResult.user;
assert(!user.isAnonymous);
assert(await user.getIdToken() != null);

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

var client = new http.Client();

obtainAccessCredentialsViaServiceAccount(accountCredentials, scopes, client)
    .then((AccessCredentials credentials) {
  // Access credentials are available in [credentials].
  // ...
  client.close();
});

return currentUser;

}

void signOut() { auth.signOut(); googleSignIn.disconnect(); }

Future getUser() async{ final FirebaseUser user = await auth.currentUser(); return user; } } `
