未创建 Firebase 应用程序“[DEFAULT]” - 仅在将图像上传到 Firebase 存储时才在 Flutter 和 Firebase 中调用 Firebase.initializeApp()

Question

我仅在 firebasestorage 中收到此错误，而不是在 firestore 中收到此错误

Pubspec.yaml 文件：

name: find_missing_people
description: A new Flutter project.
# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: "none" # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.

# The following section is specific to Flutter packages.
flutter:
  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true
  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/logo.svg
    - assets/google_logo.png
  # assets:
  #   - images/a_dot_burr.jpeg
  #   - images/a_dot_ham.jpeg
  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware
  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages
  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
    - family: Lobster
      fonts:
        - asset: fonts/Lobster-Regular.ttf

**main.dart **

import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'firebase_options.dart';

import 'utils/colors.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MyApp());
}

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'LAAPATA',
      theme: ThemeData.dark().copyWith(
        scaffoldBackgroundColor: mobileBackgroundColor,
      ),
      home: const AuthCheck(),
    );
  }
}

看起来这是产生错误的部分。 如果删除这部分，那么它就可以正常工作

final FirebaseStorage _storage = FirebaseStorage.instance;
final FirebaseFirestore _firestore = FirebaseFirestore.instance;

class StoreData {
  Future<String> uploadImage(String childName, Uint8List file) async {
    Reference ref = _storage.ref().child(childName);
    UploadTask uploadTask = ref.putData(file);
    TaskSnapshot snapshot = await uploadTask;
    String downloadUrl = await snapshot.ref.getDownloadURL();
    return downloadUrl;
  }

仅当我尝试将图像上传到 Firebase 存储时才会显示该错误。但是，如果我只是将数据上传到 firestore，它就可以工作

我也尝试过更新所有软件包，但没有任何区别

还有什么需要请告诉我吗
