    key: _androidParams.key ??
        ValueKey<AndroidWebViewWidgetCreationParams>(
            params as AndroidWebViewWidgetCreationParams),
    viewType: 'plugins.flutter.io/webview',
    surfaceFactory: (

      PlatformViewController controller,
    ) {
      return AndroidViewSurface(
        controller: controller as AndroidViewController,
        gestureRecognizers: _androidParams.gestureRecognizers,
        hitTestBehavior: PlatformViewHitTestBehavior.opaque,
      );
    },
    onCreatePlatformView: (PlatformViewCreationParams params) {
      return _initAndroidView(
        params,
        displayWithHybridComposition:
            _androidParams.displayWithHybridComposition,
        platformViewsServiceProxy: _androidParams.platformViewsServiceProxy,
