How do I control the quality of video uploaded using Flutter? - flutter

Question

In Flutter I am working on a project to upload a high definition video and then user should be able to customise the video quality just like You tube. In Flutter I am using flick_video_player, a flutter library to play the videos.
Can anyone suggest a method to do the quality control, or any library packages that has quality control of video embedded in it?
class CustomVideoPlayer extends StatefulWidget
{
CustomVideoPlayer(this.item);
final item;
createState()
{
return _CustomvideoPlayerState(this.item);
}
}
class _CustomvideoPlayerState extends State<CustomVideoPlayer>
{
_CustomvideoPlayerState(this.item);
final item;
VideoPlayerController _videoPlayerController;
FlickManager flickManager;
var url;
#override initState()
{
super.initState();
setState(()
{
SystemChrome.setPreferredOrientations([DeviceOrientation.landscapeLeft]);
url = item["video_url"].toString();
SystemChrome.setEnabledSystemUIOverlays([]);
});
flickManager = FlickManager
(
videoPlayerController: VideoPlayerController.network(url),
);
}
#override
void dispose()
{
super.dispose();
_videoPlayerController.dispose();
flickManager.dispose();
}
Widget build(BuildContext context)
{
return WillPopScope
(
child: Scaffold
(
body: SafeArea
(
// top: true,
child: Column
(
children: <Widget>
[
Expanded
(
child: Center
(
child: FlickVideoPlayer
(
systemUIOverlay: [],
preferredDeviceOrientation: [DeviceOrientation.landscapeLeft],
flickManager: flickManager,
flickVideoWithControls: FlickVideoWithControls
(
controls: LandscapePlayerControls(item),
),
),
),
),
],
),
),
),
onWillPop: onWillPopS
);
}
// Handle back press
Future<bool> onWillPopS()
{
if(flickManager.flickVideoManager.isPlaying)
{
flickManager.flickControlManager.pause();
}
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
Navigator.pop(context);
return Future.value(true);
}
}
Above is the code and I am using custom controls to play, pause and skip the videos.
Can anybody please help me with this?
