    dialogTitle: '分享时间',
    confirm: (timeBean: TimeBean) => {
      let timeHour = timeBean.timeHour
      let timeMinute = timeBean.timeMinute
      console.info(`时间选择=${timeHour}:${timeMinute}`)
      this.timeSelectorText(timeHour * 60 * 60 + timeMinute * 60)

于设置弹窗从底部弹入，从底部退出，可以参考以下demo:

@CustomDialog
struct CustomDialogExample {
  controller: CustomDialogController
  @State showFlag: Visibility = Visibility.Visible;
  build() {
    Column() {
      Button("关闭弹窗")
    }
    .width("100%")
    .height(400)
    .backgroundColor(Color.Gray)
    .onClick(() => {
      this.cancel();
    })
    .visibility(this.showFlag)
    //核心代码 设置动画事件为200ms ，设置组件转场时插入的起点和删除的终点为屏幕以下100vp
    .transition(TransitionEffect.OPACITY.animation({ duration: 200 }).combine(TransitionEffect.translate({ y: 100 })))
  }

  // 设置弹窗为隐藏，此时弹出向下退出的动效生效，再设置延时关闭弹窗。
  cancel() {
    this.showFlag = Visibility.Hidden
    setTimeout(() => {
      this.controller.close()
    }, 200)
  }
}

@Entry
@Component
struct CustomDialogUser {
  dialogController: CustomDialogController =
    new CustomDialogController({ builder: CustomDialogExample(), autoCancel: false, customStyle: true })

  build() {
    Column() {
      Button('click me').onClick(() => {
        this.dialogController.open()
      })
    }.width('100%').height('100%')
  }
}
