HarmonyOS鸿蒙Next中可以自定义CustomDialog的退出动画吗？

可以试下下面这段代码：

@CustomDialog
struct Example {
  controller: CustomDialogController = new CustomDialogController({
    builder: Example({}),
    autoCancel: false
  })
  @State showFlag: Visibility = Visibility.Visible;
  @State isAutoCancel: boolean = false;
  textController: TextAreaController = new TextAreaController()

  build() {
    Column() {
      Row() {
        TextArea({ controller: this.textController })
          .fontSize(20)
      }
      .padding(8)
      .backgroundColor('#FFFFFF')
      .height(200)
      .margin({ bottom: -5 })
      .width('100%')
    }
    .justifyContent(FlexAlign.End)
    .width('100%')
    .height("100%")
    .margin({
      bottom: -15
    })
    .onClick(() => {
      console.log("dialogClick")
      if (this.isAutoCancel) {
        console.log("dialogClick2")
        this.cancel();
      }
    })
    .visibility(this.showFlag)
    .transition(TransitionEffect.OPACITY.animation({ duration: 800 })
      .combine(TransitionEffect.translate({ y: 500 })))
  }

  cancel() {
    this.showFlag = Visibility.Hidden
    console.log("closeDialog")
    setTimeout(() => {
      this.controller.close()
    }, 800)
  }
}

@Entry
@Component
struct CustomDialogUser {
  @State isAutoCancel: boolean = true;
  dialogController: CustomDialogController = new CustomDialogController({
    builder: Example({ isAutoCancel: this.isAutoCancel }),
    autoCancel: this.isAutoCancel,
    customStyle: true
  })

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