## dart:io

The Web platform does **not** suppport `dart:io`, so attempts to create a `VideoPlayerController.file` will throw an `UnimplementedError`.

## Autoplay
Playing videos without prior interaction with the site might be prohibited
by the browser and lead to runtime errors. See also: https://goo.gl/xX8pDD.

## Supported Formats

**Different web browsers support different sets of video codecs.**

### Video codecs?

        'https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8')
      ..initialize().then((_) {
        // Ensure the first frame is shown after the video is initialized, even before the play button has been pressed.
        setState(() {});
      });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
