特殊类型的数组GetX如何监听
class NotificationLogic extends GetxController{
  ///是否开启通知权限
  var notificationPermission = false.obs;
  ///开启了哪几种通知权限
  var notificationPermissionList = <NotificationPermission>[].obs;
  ///可以开启的通知权限
  var notificationPermissionCouldAddList = <NotificationPermission>[].obs;
  ///显示的UI Widget，你可以开启xxx通知提示
  var textToShowPermissionCouldAddList = <Widget>[].obs;
}
