HarmonyOS 如何实现一个转圈效果

@Entry 
@Component 
struct AnimateToExample { 
  @State rotateAngle: number = 0 
 
  build() { 
    Column() { 
      Image($r('app.media.app_icon')) 
        .width(50) 
        .height(50) 
        .objectFit(ImageFit.Fill) 
        .margin(50) 
        .rotate({ x: 0, y: 0, z: 1, angle: this.rotateAngle }) 
        .onAppear(() => { 
          animateTo({ 
            duration: 800, 
            curve: Curve.Linear, 
            iterations: -1, // 设置-1表示动画无限循环 
          }, () => { 
            this.rotateAngle = 360 
          }) 
        }) 
    }.width('100%').margin({ top: 5 }) 
  } 
}
