警报对话框弹出未关闭。在以前，这个代码是工作，现在它不工作？当我点击取消或确认按钮后台导航工作但警报不能关闭前台是什么原因造成的问题？

Dialogs.materialDialog(

您可以根据需要使用此代码。很完美。

Future<bool?> showDeleteDialog(BuildContext context) async {
    return await showDialog<bool>(
      context: context,
      builder: (BuildContext context) {
        return AlertDialog(
          title: const Text('Delete Account'),
          content: const Text('Are you sure you want to delete your account?'),
          actions: <Widget>[
            TextButton(
              child: const Text('Cancel'),
              onPressed: () {
                Navigator.of(context).pop(false);
              },
            ),
            TextButton(
              child: const Text(
                'Delete',
                style: TextStyle(color: Colors.red),
              ),
              onPressed: () {
                Navigator.of(context).pop(true);
              },
            ),
          ],
        );
      },
    );
  }
