HarmonyOS @state修饰的变量作为判断条件 控制onTouchIntercept事件拦截，不能实时生效

可参考如下demo：scroll根据获取的手指上滑高度同步滑动list，第一次手指松开后保存list滚的状态

.onGestureJudgeBegin((gestureInfo: GestureInfo, event: BaseGestureEvent) => {
  //
  if (this.canScroll) {
    console.log(':::GestureJudgeResult.CONTINUE')
    return GestureJudgeResult.CONTINUE
  } else {
    console.log(':::GestureJudgeResult.REJECT')
    return GestureJudgeResult.REJECT
  }
})
  .onSizeChange((oldValue: SizeOptions, newValue: SizeOptions) => {
    console.info(`Ace: on size change, oldValue is ${JSON.stringify(oldValue)} value is ${JSON.stringify(newValue)}`)
    if (this.sheetHeight <= 500) {
      this.canScroll = false;
    } else {
      this.canScroll = true;
      this.scroller.scrollTo({ xOffset: 0, yOffset: this.sheetHeight-500, animation: false })
    }
  })
