尝试执行这样的构建方法：

Widget build(BuildContext context) {
return SingleChildScrollView(
  child: Column(
    children: <Widget>[
      Container(padding: const EdgeInsets.only(top: 20.0)),
      const Text('With remote mp4'),
      Container(
        padding: const EdgeInsets.all(20),
        child: AspectRatio(
          aspectRatio: _controller.value.aspectRatio,
          child: Stack(
            alignment: Alignment.bottomCenter,
            children: <Widget>[
              VideoPlayer(_controller),
              ClosedCaption(text: _controller.value.caption.text),
              _ControlsOverlay(controller: _controller),
              VideoProgressIndicator(_controller, allowScrubbing: true),
            ],
          ),
        ),
      ),
    ],
  ),
);
}
}
