HarmonyOS 有没有类似与Vue中this.$nextTick的方法？

this.getUIContext().getUIInspector().createComponentObserver("Page13HelloWorld").on("draw", () => { 
  console.log("testTag - draw") 
  let utils = this.getUIContext().getComponentUtils() 
  let com = utils.getRectangleById("Page13HelloWorld") 
  console.log("testTag - draw - height : "+ com.size.height );
