HarmonyOS ArkUI支持类似css中drop-shadow的阴影效果吗？

@Entry  
@Component  
struct WebComponent {  
  build() {  
    Column() {  
      Text('shadow').fontSize(15).fontColor(0xCCCCCC).width('90%')  
      Circle()  
        .width(50)  
        .height(50)  
        .shadow(  
          {  
            radius: 100,  
            color: Color.Green,  
            offsetX: 20,  
            offsetY: 20,  
            fill: true  
          }  
        ).opacity(0.5)  
    }  
  }  
}
