Flutter web - horizontal singlechildscrollview cannot scroll with mouse wheel
461
Wrap your inner SingleChildScrollView with Listener and add onPointerSignal callback, and you can get a offset in y axis when use mouse wheel. Then, scroll inner SingleChildScrollView and forbid outer ListView from scrolling. Here is my code and it works on dartpad.
final outerController = ScrollController();
final innerController = ScrollController();
ListView(
controller: outerController,
children: [
Container(
width: 420.0,
child: Row(
children: [
Expanded(
child: Text(
'Popular Search',
),
),
Expanded(
flex: 3,
child: Listener(
onPointerSignal: (event) {
if (event is PointerScrollEvent) {
final offset = event.scrollDelta.dy;
innerController.jumpTo(innerController.offset + offset);
outerController.jumpTo(outerController.offset - offset);
}
},
child: SingleChildScrollView(
controller: innerController,
scrollDirection: Axis.horizontal,
child: Row(
children: categoriesList.map((e) {
return Container(
decoration: BoxDecoration(
borderRadius:
BorderRadius.all(Radius.circular(12.0)),
color: Colors.white,
),
child: Text(
e,
style: TextStyle(
fontSize: 13.0,
),
),
);
}).toList(),
),
),
))
],
),
),
],
),

I want to scroll a SingleChildScrollView() horizontally with mouse wheel in Flutter web but the SingleChildScrollView() is inside a ListView() and when i try to scroll it with the mouse wheel it scrolls the ListView().
This is my code
child: ListView( children: [ Container( width: 420.0, child: Row( children: [ Expanded( child: Text( 'Popular Search', ), ), Expanded( flex: 3, child: SingleChildScrollView( scrollDirection: Axis.horizontal, child: Row( children: categoriesList.map((e) { return Container( decoration: BoxDecoration( borderRadius: BorderRadius.all(Radius.circular(12.0)), color: Colors.white, ), child: Text( e, style: TextStyle( fontSize: 13.0, ), ), ); }).toList(), ), ), ) ], ), ), ], ),

Soorya over 2 yearsI'm also facing the same issue. I tried this stackoverflow.com/questions/69154468/… answer but did not work for me. Let me know if you found a solution. As a quick fix, I added a scrollbar & made it always visible for scrolling.
