FirebaseError：Firebase：未创建 Firebase 应用程序“[DEFAULT]” - 首先调用initializeApp（）（应用程序/无应用程序）。颤抖中

Question

我正在尝试在 chrome 网络版上运行我的 flutter 应用程序。但每次我运行我的颤振代码时。遇到以下错误。

我已将

google-services.json

添加到

<Project>/android/app/

我的应用程序在我的物理设备和应用程序版本的模拟器上运行没有任何错误

我的问题仅在于这个颤振代码的网络。在其他平台（Android、Windows 等）中，代码运行良好

代码在

main.dart

import 'package:attandance_seventh/firebase_options.dart';
import 'package:attandance_seventh/globals/bindings.dart';
import 'package:attandance_seventh/services/remote/firestore/notification.dart';
import 'package:attandance_seventh/views/launch_screen/launch_screen.dart';
import 'package:flutter/material.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';
import 'package:get/get.dart';
import 'package:get_storage/get_storage.dart';
// ignore: depend_on_referenced_packages
import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await ScreenUtil.ensureScreenSize();
  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
  await initNotification();
  await GetStorage.init();
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return ScreenUtilInit(
      minTextAdapt: true,
      splitScreenMode: true,
      builder: (context, child) {
        return GetMaterialApp(
          title: 'Flutter Demo',
          initialBinding: GlabalBindings(),
          debugShowCheckedModeBanner: false,
          theme: ThemeData(
            primarySwatch: Colors.blue,
          ),
          // home: const SplashScreen(),
          home: Scaffold(
            body: Center(
              child: Text('Hello kids'),
            ),
          ),
        );
      },
    );
  }
}

代码在

您可以指定

Options

值。

options: const FirebaseOptions(
            apiKey: "AIzaSyD3ZbXXXXXXXXXXXXXXX-XXXX",
            authDomain: "XXXXXXXXXX.firebaseapp.com",
            projectId: "XXXXXXX",
            storageBucket: "XXXXXXXX.appspot.com",
            messagingSenderId: "XXXXXXXXX",
            appId: "1:XXXXXX:web:XXXXXXXX",
            measurementId: "G-XXXXXXX")
