HarmonyOS Toggle是否有异步控制功能

示例如下：

@Entry
@Component
struct ToggleExample {
  @State openShow:boolean=false
  build() {
    Column({ space: 10 }) {
      Text('type: Switch').fontSize(12).fontColor(0xcccccc).width('90%')
      Flex({ justifyContent: FlexAlign.SpaceEvenly, alignItems: ItemAlign.Center }) {
        Toggle({ type: ToggleType.Switch, isOn: $$this.openShow })
          .selectedColor('#007DFF')
          .switchPointColor('#FFFFFF')
          .onChange((isOn) => {
            if(isOn){
              AlertDialog.show({
                title: '用户确认是否开启',
                message: 'text',
                buttons:[
                  {
                    value: '确认',
                    action: () => {
                      console.info('Callback when button1 is clicked')
                    }
                  },
                  {
                    value: '取消',
                    action: () => {
                      this.openShow=false
                    }
                  },
                ]
              })

            }
          }).hoverEffect(HoverEffect.None)
      }
    }.width('100%').padding(24)
  }
}
