HarmonyOS 属性动效如何打断

另外起一个duration为0的动画在新的动画闭包中修改对应的属性来停掉之前的属性动画，示例代码如下：

@Entry
@Component
struct Page240119142354017 {
  @State message: string = ‘Hello World’;
  @State opacityValue: number = 1
  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .opacity(this.opacityValue)
        Button(“开始动画”).onClick(() => {
          animateTo({ duration: 1000, iterations: -1, playMode: PlayMode.AlternateReverse }, () => {
            this.opacityValue = 0
          })
        })
        Button(“结束动画”).onClick(() => {
          animateTo({
            duration: 0, iterations: 1, onFinish: () => {
              this.opacityValue = 1
            }
          }, () => {
            this.opacityValue = 0.9
          })
        })
      }
      .width(‘100%’)
    }
    .height(‘100%’)
  }
}
