如何在 flutter 的页面浏览小部件中同时滚动两种方式？

Question

I am using PageView for my application. PageView has a property of scrollDirection which sets the scroll either horizontal or vertical . code example:

 Widget build(BuildContext context) {
    return PageView.builder(
        scrollDirection: Axis.horizontal,
        itemBuilder: (context, position) {
          return Container(
            color: Colors.black,
            child: Stack(
              children: <Widget>[AppVideoPlayer(), onScreenControls()],
            ),
          );
        },
        itemCount: 20);
  }

Is there a way where PageView can be set to scroll both ways (horizontal and vertical) at the same time. If not, then is there any way in which this can be achieved?

  Widget build(BuildContext context) {
    return PageView.builder(
        scrollDirection: Axis.vertical,
        itemBuilder: (context, position) {
          return PageView.builder(
        scrollDirection: Axis.horizontal,
        itemBuilder: (context, position) {
          return Container(
            color: Colors.black,
            child: Stack(
              children: <Widget>[AppVideoPlayer(), onScreenControls()],
            ),
          );
        },
        itemCount: 20);
        },
        itemCount: 20);
  }
