How to Detect scroll on the widget underneath the stack?












0














I am trying to implement GuillotineMenu as per this tutorial and I managed to create the awesome animated menu but the listview below the menu does not detect the gesture(scroll). How can I send the scroll gesture to the listview? when I use IgnorePointer on the menu the scroll works but the menu does not. I can I detect gestures on both widgets on stack?



P.S In this code I have used gesture detector instead of listview



code:



home.dart



import 'package:Pixelitg/GuillotineMenu.dart';
import 'package:flutter/material.dart';

class Home extends StatefulWidget {
@override
_HomeState createState() => new _HomeState();
}

return SafeArea(
top: false,

      I am trying to implement GuillotineMenu as per this tutorial and I managed to create the awesome animated menu but the listview below the menu does not detect the gesture(scroll). How can I send the scroll gesture to the listview? when I use IgnorePointer on the menu the scroll works but the menu does not. I can I detect gestures on both widgets on stack?



      P.S In this code I have used gesture detector instead of listview



      code:



      home.dart



      import 'package:Pixelitg/GuillotineMenu.dart';
      import 'package:flutter/material.dart';

      class Home extends StatefulWidget {
      @override
      _HomeState createState() => new _HomeState();
      }

      class _HomeState extends State<Home> {
      @override
      Widget build(BuildContext context) {
      return SafeArea(
      top: false,
      bottom: false,
      child: new Container(
      child: new Stack(
      alignment: Alignment.topLeft,
      children: <Widget>[
      new Page(),
      new GuillotineMenu(),
      ],
      ),
      ),
      );
      }
      }
