我通过使用drawer和ListTile成功地实现了侧边栏菜单，但问题是当ListTile点击并关闭drawer时，我重新打开drawer会看到点击的ListTile将重置为未点击的颜色。如何解决这一问题？我试了很多次，但我找不到解决办法。
菜单列表箭头文件

class MenuList extends StatefulWidget {
  final Function(int, String) onTap;

  List<Map<String, dynamic>> menu = [];
  MenuList({required this.onTap, required this.menu});

  @override
  State<MenuList> createState() => _MenuListState();
}

class _MenuListState extends State<MenuList> {
  int _selectedIndex = 0;

  Widget buildListTile(Map<String, dynamic> item, int index) {
    return ListTile(
      title: Text(
        item["title"],
        style: TextStyle(
            color: _selectedIndex == index ? Colors.deepOrangeAccent : Colors.grey,
        ),
      ),
      leading: Icon(
        item['leading'],
        color: _selectedIndex == index ? Colors.deepOrangeAccent : Colors.grey,
      ),
      tileColor: Colors.white,
      onTap: (){
        setState(() {
          _selectedIndex = index;
        });
        widget.onTap(index, item['title']);
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ListView.builder(
        itemCount: widget.menu.length,
        itemBuilder: (BuildContext context, int index) {
          return buildListTile(widget.menu[index], index);
        },
      ),
    );
  }
}
