Flutter: GoogleSignIn बिना क्रिया के अपवाद

मुझे GoogleSignIn प्लगइन का उपयोग करके एक अजीब समस्या का सामना करना पड़ रहा है, मैंने अभी कुछ महीनों के लिए Google साइनइन का उपयोग नहीं किया है, और जब मैंने इस समस्या का सामना किया तो मैंने आज इसे फिर से तार करने का फैसला किया।

मैं निम्नलिखित परीक्षण कोड का उपयोग कर रहा हूँ:

google_sign_in: "^1.0.1"
  firebase_auth: "^0.2.3"

import 'dart:async';

import "package:flutter/material.dart";
import "package:firebase_auth/firebase_auth.dart";
import "package:google_sign_in/google_sign_in.dart";


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

 _testSignInWithGoogle() async {
  final GoogleSignInAccount googleUser = await _googleSignIn.signIn();
  final GoogleSignInAuthentication googleAuth =
  await googleUser.authentication;
  final FirebaseUser user = await _auth.signInWithGoogle(
    accessToken: googleAuth.accessToken,
    idToken: googleAuth.idToken,
  );
  print (googleUser.displayName);
  return (user);
}
class TestSignIn extends StatefulWidget {
  <strong i="9">@override</strong>
  _TestSignInState createState() => new _TestSignInState();
}

class _TestSignInState extends State<TestSignIn> {
   <strong i="10">@override</strong>
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(title: new Text("test"),
      ),
      body: new Column(
        children: <Widget>[
          new FlatButton(onPressed: ()=>_testSignInWithGoogle(), child: new Text("Test SignIn Google"),),
          //print user
        ],
      )
    );
  }
}

मुझे नहीं लगता कि यह समस्या अगर फायरबेस की तरफ से है। फायरबेस मेरे ऐप के साथ सही ढंग से कॉन्फ़िगर किया गया है और उपयोगकर्ता नाम/पासवर्ड के साथ ठीक काम करता है।
