HarmonyOS flutter中path_provider等依赖原生功能的模块如何正确引入？

目前报错：

PlatformException(channel-error, Unable to establish connection on channel., null, null) 

现在的方案是更改 .ohos/entry/src/main/ets/entryability/EntryAbility.ets为：

import { GeneratedPluginRegistrant } from '@ohos/flutter_module'

import { FlutterAbility, FlutterEngine } from '@ohos/flutter_ohos'

export default class EntryAbility extends FlutterAbility {
  configureFlutterEngine(flutterEngine: FlutterEngine) {
    super.configureFlutterEngine(flutterEngine);
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

不知是否合理？是否还有更合理的方案？
