        context: context,
        builder: (context) {
          return CupertinoAlertDialog(
            title: Text('退出当前模式'),//不想有输入框直接去掉即可
            content: Card(
              elevation: 0.0,
              child: Column(
                children: <Widget>[
                  TextField(
                    onChanged: (v) => _password = v,
                    decoration: InputDecoration(
                      hintText: "请输入",
                    ),
                  ),
                ],
              ),
            ),
            actions: <Widget>[
              CupertinoDialogAction(
                onPressed: () {
                  Navigator.pop(context);//关闭当前弹窗
                },
                child: Text('取消'),
              ),
              CupertinoDialogAction(
                onPressed: () {
                  Navigator.of(context).pop();//先关闭再跳转页面
                  _back(_password);
                },
                child: Text('确定'),
