My application is unable to perform scrolling operations using ListView on Linux tablets #147277
Description
Steps to reproduce
My application is unable to perform gesture-based scrolling using ListView on Linux tablets, but it can be scrolled using a mouse. Additionally, all these operations work fine on Windows tablets. I am using Flutter SDK version 3.7.1
I upgraded to the latest 3.19.6 and experienced the same problem
Expected results
listview supports gesture sliding on Linux tablets
Actual results
The listview does not support gesture swiping on Linux tablets
Code sample
class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;
void _incrementCounter() {
setState(() {
// This call to setState tells the Flutter framework that something has
// changed in this State, which causes it to rerun the build method below
// so that the display can reflect the updated values. If we changed
// _counter without calling setState(), then the build method would not be
// called again, and so nothing would appear to happen.
_counter++;
});
}
@override
Widget build(BuildContext context) {
// This method is rerun every time setState is called, for instance as done
// by the _incrementCounter method above.
//
// The Flutter framework has been optimized to make rerunning build methods
// fast, so that you can just rebuild anything that needs updating rather
// than having to individually change instances of widgets.
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(widget.title),
),
body: Center(
// Center is a layout widget. It takes a single child and positions it
// in the middle of the parent.
child: ListView(
children:this._getdata(),
)
),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: const Icon(Icons.add),
), // This trailing comma makes auto-formatting nicer for build methods.
);
}
List<Widget> _getdata(){
List<Widget> list=[];
for(var i=0;i<20;i++){
list.add(ListTile(
title: Text("item $i"),
));
}
return list.toList();
}
