      drawerEnableOpenDragGesture: true,
      appBar: AppBar(
      
        title: Text('Relatório'),
        actions: <Widget>[
            IconButton(
              icon: Icon(Icons.filter_list_outlined),
               onPressed: () => _key.currentState?.openEndDrawer(), 
            ),
          ],
          
      ),
      endDrawer: Drawer(
        key: _key,
        child: Container(
          width: 100,
          height: 100,
        ),
      ),
    );
  }

As you guys can see my code is not responding as expected. give me suggestions.

CodePudding user response：

You need to provide the key on Scaffold instead of Drawer widget.

   return Scaffold(
      key: _key,

 Widget build(BuildContext context) {
    final GlobalKey<ScaffoldState> _key = GlobalKey();
    return Scaffold(
      key: _key,
      drawerEnableOpenDragGesture: true,
      appBar: AppBar(
        title: Text('Relatório'),
        actions: <Widget>[
          IconButton(
            icon: Icon(Icons.filter_list_outlined),
            onPressed: () => _key.currentState?.openEndDrawer(),
          ),
        ],
      ),
      endDrawer: Drawer( //not here 
        child: Container(
          width: 100,
          height: 100,
        ),
      ),
    );
  }
