Flutter Firebase：测试在 initalizeApp() 上挂起

Question

我有一个我正在尝试测试的小部件，它依赖于 Firestore 存储库。 代码如下：

void main() {
  group('AdminVerificationScreen', () {
    testWidgets('renders correctly', (WidgetTester tester) async {
      WidgetsFlutterBinding.ensureInitialized();

      //pump the widget using a bloc provider and a multirepository provider
      await Firebase.initializeApp(
        options: DefaultFirebaseOptions.currentPlatform,
      );

      await tester.pumpWidget(
        MultiRepositoryProvider(
          providers: [
            RepositoryProvider(
              create: (_) => FirestoreRepository(),
            ),
            RepositoryProvider(
              create: (context) => TypesenseRepository(),
            ),
          ],
          child: MultiBlocProvider(
            providers: [
              BlocProvider<AdminVerificationBloc>(
                create: (context) => AdminVerificationBloc(
                    databaseRepository: context.read<FirestoreRepository>(),
                    typesenseRepository: context.read<TypesenseRepository>()),
              ),
            ],
            child: MaterialApp(
              home: AdminVerificationScreen(),
            ),
          ),
        ),
      );

      //expect the widget to be found
      expect(find.byType(AdminVerificationScreen), findsOneWidget);
    });
  });
}

问题出在初始化应用程序上。 它被挂断并且不会继续，但是删除它会出现错误：

[core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()

有人看到我做错了什么吗？

谢谢！

看起来您在调用main()后缺少async ，因此您没有给 Firebase 完成其初始化的机会。

试试这个：

Future<void> main() async {
...
