import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/material.dart';
import 'package:telegramchatapp/Pages/HomePage.dart';
import 'package:telegramchatapp/Widgets/ProgressWidget.dart';
import 'package:fluttertoast/fluttertoast.dart';
import 'package:google_sign_in/google_sign_in.dart';
import 'package:shared_preferences/shared_preferences.dart';

  @override
  LoginScreenState createState() => LoginScreenState();
}



class LoginScreenState extends State<LoginScreen> {

  final FirebaseAuth firebaseAuth = FirebaseAuth.instance;
  SharedPreferences preferences;

  bool isLoggedIn = false;
  bool isLoading = false;
  FirebaseUser currentUser;

  @override
  void initState() {
    // TODO: implement initState …
