场景

当调用getx的底部弹窗 Get.bottomSheet 弹起后 关闭弹窗没有相应的回调

方式一

isDismissible 是 关闭点击空白区域自动关闭 设置为flase,然后

在内部添加 关闭按钮Get.back(); 的时候执行父组件传递进来的onClose 自定义事件

上面这种方式有缺陷： 系统返回键也可关闭弹窗。返回事件没有调用；

方式二

Get.bottomSheet 返回一个future

在await Get.bottomSheet 之后进行弹窗判断 Get.isBottomSheetOpen == false 说明弹窗已经关闭了 然后做逻辑处理

代码如下（因为有封装 有点复杂）

Alert class

class Alert {
  static final ClickHandler clickHandler = ClickHandler();

  //
  static showPersonInfo(
    SelfController cc, {
    Function()? onClose,
  }) {
    return AppToast.showAlert(height: 290.h, title: "", onClose: () {
      onClose?.call();
