HarmonyOS版flutter_inappwebview不能正常显示网页

使用FlutterEntry，在EntryAbility中注册插件是无效的。FlutterEntry中的插件注册参考代码：

class ceFlutterEntry extends FlutterEntry {
  configureFlutterEngine(flutterEngine: FlutterEngine): void {
    super.configureFlutterEngine(flutterEngine);
    GeneratedPluginRegistrant.registerWith(flutterEngine);
    this.delegate?.addPlugin(new BaseFlutterPlugin());
  }
}

@Component
export struct ceFlutterPage {
  // ...
  aboutToAppear(): void {
    // ...
    this.flutterEntry = new ceFlutterEntry(getContext(this), params);
    // ...
  }
  // ...
}
