Hydrod_bloc：参数“storageDirectory”是必需的

Question

我将 Hydrated_bloc 从 6.1.0 更新到最新的 7.0.1，并收到警告：

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.

我也尝试过：

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

Answer 1

和getTemporaryDirectory都是path_providergetApplicationDocumentsDirectory包的一部分，因此，您必须将其导入到 main.dart 文件中
