How can you detect mouse wheel scroll in flutter web? It seems like it would be in a gesture detector but I don't see it in there. How do list views detect mouse scroll?

Wrap your ListView (or any other scroll view) with Listener and listen for PointerScrollEvent:

Listener(
  onPointerSignal: (pointerSignal){
    if(pointerSignal is PointerScrollEvent){
      // do something when scrolled
      print('Scrolled');
    }
  },
  child: ... //your scrollview here
)
