Question

我有一个具有两个平台视图的应用程序，其中一个是Doodle视图，另一个是webview，下面是我的代码

Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('test'),
      ),
      body: BlocProvider<CourseDocBloc>(
        create: (context) => CourseDocBloc(),
        child: Container(
          height: double.infinity,
          child: Stack(
            children: <Widget>[
              Listener(
                child: WebView(
                  initialUrl: 'https://google.com',
                  javascriptMode: JavascriptMode.unrestricted,
                  onPageStarted: (url) {
                    print('start load');
                  },
                  onPageFinished: (url) {
                    print('load finished');
                  },
                ),
               onPointerDown: (e) => {print('web down')},
               onPointerUp: (e) => {print('web up')},
              ),
              UiKitView(
                viewType: 'GLView',
                hitTestBehavior: PlatformViewHitTestBehavior.transparent, 
                onPlatformViewCreated: (_) => created(),
              )
            ],
          ),
        ),
      ),
    );
  }

当我设置UiKitView hitTestBehavior: PlatformViewHitTestBehavior.transparent时，底部的Listener将打印web down, web up ...，但是WebView无法接收触摸事件，我无法输入然后单击html中的按钮。 GLView只是用于渲染Doodle的OpenGL视图。

检查一下 https://stackoverflow.com/a/55431380

使用IgnorePointer包装窗口小部件时，该窗口小部件的所有触摸事件都会传递到其下方的窗口小部件。

child: Stack(
            children: <Widget>[
              Listener(
                child: WebView(
                  initialUrl: 'https://google.com',
                  javascriptMode: JavascriptMode.unrestricted,
                  onPageStarted: (url) {
                    print('start load');
                  },
                  onPageFinished: (url) {
                    print('load finished');
                  },
                ),
               onPointerDown: (e) => {print('web down')},
               onPointerUp: (e) => {print('web up')},
              ),
              IgnorePointer(
                child: UiKitView(
                 viewType: 'GLView',
                 hitTestBehavior: PlatformViewHitTestBehavior.transparent, 
                 onPlatformViewCreated: (_) => created(),
               ),
             ),
            ],
          ),
