How to: Stop ListView from rebuilding video_player widget? - flutter

Question

I have managed to get a video to play on flutter-web, however, when I scroll the video in the ListView will rebuild/reload.
How can I stop the video_player (in the ListView) from being rebuilt when I scroll?
Sorry for the lengthy code sample.. I'm not sure how to condense it further
Any help would be great! Thanks
import 'package:flutter/material.dart';
import '../../widgets/video/chewie_video.dart';
import 'package:video_player/video_player.dart';
class TestPage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: ListView(
children: <Widget>[
Container(height: 1000),
Center(
child: ChewieVideo(
videoPlayerController:
VideoPlayerController.asset('assets/video.mp4'),
),
),
Container(height: 1000),
],
),
);
}
}
import 'package:chewie/chewie.dart';
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';
class ChewieVideo extends StatefulWidget {
final VideoPlayerController videoPlayerController;
final bool looping;
ChewieVideo({
#required this.videoPlayerController,
this.looping,
Key key,
}) : super(key: key);
#override
_ChewieVideoState createState() => _ChewieVideoState();
}
class _ChewieVideoState extends State<ChewieVideo> {
ChewieController _chewieController;
#override
void initState() {
super.initState();
_chewieController = ChewieController(
videoPlayerController: widget.videoPlayerController,
autoInitialize: true,
aspectRatio: 16 / 9,
looping: widget.looping,
errorBuilder: (context, errorMessage) {
return Center(
child: Text(
errorMessage,
style: TextStyle(color: Colors.white),
),
);
},
);
}
#override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.all(8.0),
child: Chewie(
controller: _chewieController,
),
);
}
#override
void dispose() {
super.dispose();
widget.videoPlayerController.dispose();
_chewieController.dispose();
}
}

I'm not sure if this is a good or just temporary fix but this is how I have managed to get it to work...
If you are using inside of a ListView/CustomScrollView, then you need to adjust the cacheExtent for either of these widgets... I have set mine to 1000.
I'm not quite sure what's happening but it works...
class HomePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: primaryBlack,
drawer: NavDrawer(),
body: Scrollbar(
child: CustomScrollView(
cacheExtent: 1000,
slivers: <Widget>[
...
after doing that chewie and video_player plugins shouldn't rebuild/refresh inside of a ListView
