HarmonyOS 鸿蒙Next CustomDialog是否支持自定义动画？

CustomDialog支持自定义动画 ,可以参考以下demo：

let anmDuration: number = 800;
// 弹窗交互
@CustomDialog
struct CustomDialogExample {
  @State showFlag: Visibility = Visibility.Visible;
  @State isAutoCancel: boolean = false;
  controller: CustomDialogController = new CustomDialogController({
    builder: CustomDialogExample({}),
    autoCancel: false
  })
  build() {
    Column() {
      Text('我是内容')
        .fontSize(20)
        .margin({ top: 10, bottom: 10 })
        .backgroundColor('#FFFFFF')
        .textAlign(TextAlign.Center)
        .height(200)
        .width('100%')
        .onClick(() => {
          this.cancel();
        })
    }
    .width('100%')
    .height('100%')
    .margin({
      bottom: -15
    })
    .onClick(() => {
      if (this.isAutoCancel) {
        this.cancel();
      }
    })
    .visibility(this.showFlag)
    // 定义进场出场转场动画效果
    .transition(TransitionEffect.OPACITY.animation({ duration: anmDuration })
      .combine(TransitionEffect.translate({ x: 0, y: 100 })))
  }
  // 延迟关闭弹窗，让自定义的出场动画显示
  cancel() {
    this.showFlag = Visibility.Hidden
    setTimeout(() => {
      this.controller.close()
    }, anmDuration)
  }
}
@Entry
@Component
struct CustomDialogUser {
  // 是否允许点击遮障层退出
  @State isAutoCancel: boolean = true;
  dialogController: CustomDialogController = new CustomDialogController({
    builder: CustomDialogExample({ isAutoCancel: this.isAutoCancel }),
    autoCancel: this.isAutoCancel,
    // 弹窗容器样式是否自定义
    customStyle: true
  })
  build() {
    Column() {
      Button('点我')
        .onClick(() => {
          this.dialogController.open()
        })
    }.width('100%').height('100%').margin({ top: 5 })
  }
}
