Flutter – Firebase connection error, call firebase.initializeApp() error in but i already initialized it

screenshot of error

I was trying to setup firebase auth and done all the steps but i am new to it and other yt tutorials covers something from previous versions and there are some changes inside build gradle app and project level, i think i’d done pretty much everything but there is an error of initializing app. Please guide me what could be the problem and what could i do in this point?

my main.dart

import 'package:ecom/signup.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

import 'provider/cart_provider.dart';
import 'provider/favourite_provider.dart';

// void main() async {
//   WidgetsFlutterBinding.ensureInitialized();
//   await Firebase.initializeApp();
//   runApp(const MyApp());
// }

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  try {
    print("Firebase initialized successfully");
    await Firebase.initializeApp();
  } catch (e) {
    print("Failed to initialize Firebase: $e");
  }
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) => MultiProvider(
        providers: [
          ChangeNotifierProvider(create: (_) => CartProvider()),
          ChangeNotifierProvider(create: (_) => FavoriteProvider()),
        ],
        child: MaterialApp(
          title: 'Flutter Demo',
          debugShowCheckedModeBanner: false,
          theme: ThemeData(
            colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
            useMaterial3: true,
          ),
          home: const sign_up(),
        ),
      );
}
