hydrated_bloc：需要参数'storageDirectory'

Question

我将 hydrated_bloc 从 6.1.0 更新到最新的 7.0.1，我在以下位置收到警告：

HydratedBloc.storage = await HydratedStorage.build(); The parameter 'storageDirectory' is required.

当我更改为新文档建议的内容时

HydratedBloc.storage = await HydratedStorage.build(
storageDirectory: await getTemporaryDirectory(),); The function 'getTemporaryDirectory' isn't defined.

我也试过：

HydratedBloc.storage = await HydratedStorage.build(storageDirectory: await getApplicationDocumentsDirectory(),); The function 'getApplicationDocumentsDirectory' isn't defined

Answer 1

getTemporaryDirectory 和 getApplicationDocumentsDirectory 都是 path_provider 包的一部分，因此，您必须将其导入 main.dart 文件

Answer 2

是的，您需要路径 Provider Flutter package，您可能还会遇到此错误“StorageNotFound（存储在初始化之前已被访问），或者未定义 setter 'storage' Android Studio 中的类型 'HydratedBloc' 而是将其定义如下：`

 void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  final storage = await HydratedStorage.build(
    storageDirectory: await getApplicationDocumentsDirectory(),
  );
  HydratedBlocOverrides.runZoned(
    () => runApp(MyApp(
      appRouter: AppRouter(),
      connectivity: Connectivity(),
    )),
    storage: storage,
  );
}
