Here i tried to reproduce your issue but there is no crash
I'm also using large desktop wallpaper image
Code Sample
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Material App',
home: Home(),
);
}
}
class Home extends StatefulWidget {
@override
_HomeState createState() => _HomeState();
}
class _HomeState extends State<Home> {
ScrollController _controller;
@override
void initState() {
_controller = ScrollController();
super.initState();
}
@override
void dispose() {
_controller.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
// Here we take the value from the MyHomePage object that was created by
// the App.build method, and use it to set our appbar title.
title: Text('App'),
actions: <Widget>[
// NEW
IconButton(
// NEW
icon: Icon(Icons.arrow_downward),
onPressed: null) // NEW
],
),
body: GridView.builder(
controller: _controller,
itemCount: 500,
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 3,
mainAxisSpacing: 20.0,
crossAxisSpacing: 10.0,
childAspectRatio: 1.0),
itemBuilder: (context, index) {
int count = index % 75;
return Container(
child: Image.asset('assets/wallpaper.jpg'),
);
}),
floatingActionButton: FloatingActionButton(
onPressed: () {
// Navigator.push<DecorationScreen>(context,
// new MaterialPageRoute(builder: (context) => DecorationScreen()));
},
tooltip: 'Increment',
child: Icon(Icons.add),
), // This trailing comma makes auto-formatting nicer for build methods.
);
}
}
can you please provide your flutter doctor -v and flutter run --verbose?
Also, to better address the issue, would be helpful if you could post a minimal code sample to reproduce the problem with all the code
Thank you

I write a demo to display image using gridview. Here is my demo:
Image is placed under local asset fold, every image is every large(1920*1200), if I scroll the gridview quickly, it will crash soon. The following is my flutter doctor information.

It seems that there are too many image decoded, and posted to io runner, but io runner is very busy, it can't upload raster image to gpu and return in time. Could someone help me to look at it, thanks very much
