Try to listen listview drag end event

Hello,
I am build a list with listview.builder

And use control to listener the scroll position,

I try to get drag release position, when drag down pass some position point, when user release drag , will process function.

When doing the research I haven’t see any information about listview drag start and drag end event maybe there wasn’t have one?

And I try other method was wrap listview inside gestures , tap event is working but all drag vertical event is not working. :(

just found out a solution using listener.

wrap listview inside listener.

return new Scaffold(
        appBar: appBar,
        body: new Listener(
            onPointerUp: (_) {
              tabup = true;
            },
            onPointerDown: (_) {
              tabup = false;
            },
            child:  put listview here
));
  }

  }

Thanks for the code snippet and no need to wrap Listener with Scaffold.
