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,
        ),
      ),
    );
  }
