在Flutter中点击另一个项目ListView后，如何取消选择已经选中的项目？

class MyListView extends StatefulWidget {
  @override
  _MyListViewState createState() => _MyListViewState();
}

class _MyListViewState extends State<MyListView> {
  List<bool> _selectedItems = List.generate(10, (index) => false);

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: 10,
      itemBuilder: (context, index) {
        return GestureDetector(
          onTap: () {
            setState(() {
              _selectedItems[index] = !_selectedItems[index];
              // 如果只能选择一个项目，取消其他项目的选中状态
              for (int i = 0; i < _selectedItems.length; i++) {
                if (i != index) {
                  _selectedItems[i] = false;
                }
              }
            });
          },
          child: Container(
            color: _selectedItems[index] ? Colors.blue : Colors.white,
            child: ListTile(
              title: Text('Item $index'),
            ),
          ),
        );
      },
    );
  }
}
