4 years ago Hi,
Never got that ! I'll try to take a look asap!
For the performance are you talking in debug or release mode ? Because yes performances are shity (app wide) in debug mode, but I don't have any trouble in release mode.

4 years ago @jaumard Yep, sorry. I have tried using it in my other simple application. It runs fast. So I think maybe my previous project that was too long, and the performance was affected.

3 years ago Should be fixed on 1.3.0
I using this Mjpeg widget but it throws the following exception continuously...
or
In addition, when I include this Mjpeg widget in ListView (at least 5 items), my application runs very very slowly. Is it because of the poor performance of this widget?
My code snippet:
```dart import 'package:flutter/material.dart'; import 'package:flutter_mjpeg/flutter_mjpeg.dart'; class MyHomePage extends StatelessWidget { Widget build(BuildContext context) { var urlList = List.generate(255, (index) => "http://192.168.1.$index/stream"); return Scaffold( appBar: AppBar(title: Text("MJPEG")), body: Center( child: Container( width: double.infinity, height: 120, color: Colors.black12, child: ListView.builder( scrollDirection: Axis.horizontal, itemCount: urlList.length, itemBuilder: (BuildContext context, int index) => Container( margin: EdgeInsets.only(right: 10), width: 214, height: 120, color: Colors.black, child: Mjpeg( stream: urlList[index], isLive: true, fit: BoxFit.fill, error: (_, error) => Center(child: Text(error.toString(), style: TextStyle(color: Colors.red))), loading: (_) => Center(child: CircularProgressIndicator()) ) ) ) ) ) ); } } ```flutter doctor -v
