我在 Dart 项目中使用 @injectableInit 进行依赖项注入的自动生成代码遇到问题。该代码旨在使用 GetIt 初始化依赖项，但在创建特定类型 (HomeBloc) 期间会导致“错误状态”错误。该错误表明 Dio 类型的对象/工厂未在 GetIt 内注册。有趣的是，当我切换到手动注入时，代码可以完美运行。
自动生成代码。
@injectableInit
GetIt initDI(GetIt getIt) => getIt.init();
错误：-
════════ Exception caught by widgets library ═══════════════════════════════════
Bad state: Tried to read a provider that threw during the creation of its value.
The exception occurred during the creation of type HomeBloc.
══╡ EXCEPTION CAUGHT BY PROVIDER ╞═══════════════════════════════
The following StateError was thrown:
Bad state: GetIt: Object/factory with type Dio is not registered
inside GetIt.
(Did you accidentally do GetIt sl=GetIt.instance(); instead of
GetIt sl=GetIt.instance;
Did you forget to register it?)

但是当我使用手动注入时，它工作正常，任何人都可以帮助我解决这个问题吗？
@injectableInit
void initDI(GetIt getIt) {
final dio = Dio(); // Create a Dio instance
getIt.registerSingleton<Dio>(dio); // Register it as a singleton
getIt.registerSingleton<AppRouter>(AppRouter()); // Register it as a singleton
getIt.registerSingleton<ApiProvider>(ApiProvider(dio)); // Register it as a singleton
getIt.registerSingleton<HomeBloc>(HomeBloc(ApiProvider(dio))); // Register it as a singleton
}
尝试将实例从 getIt 传递到构造函数中：
@injectableInit
void initDI(GetIt getIt) {
getIt.registerSingleton(Dio())
..registerSingleton(AppRouter())
..registerSingleton(ApiProvider(getIt<Dio>()))
..registerSingleton(HomeBloc(getIt<ApiProvider>()));
}
