HarmonyOS List容器删除item时，是否支持动效

可以使用ListItem的transition属性实现，参考示例：

@Entry
@Component
struct ListItemExample {
  @State arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
  private scroller: Scroller = new Scroller()
  startIndex: number = 10

  build() {
    Column() {
      List({ space: 20, scroller: this.scroller }) {
        ForEach(this.arr, (item: number) => {
          ListItem() {
            Text('' + item)
              .width('100%')
              .height(100)
              .fontSize(16)
              .textAlign(TextAlign.Center)
              .borderRadius(10)
              .backgroundColor(0xFFFFFF)

          }
          .transition({ type: TransitionType.Delete, opacity: 0 })

        }, (item: string) => item)
      }.width('90%').scrollBar(BarState.Off)


      Button('删除')
        .width(100)
        .height(100)
        .onClick(() => {

          animateTo({ duration: 500 }, () => {
            // let index = this.arr.indexOf(item)
            // this.arr.splice(index, 1)
            if (this.arr.length > 0) {
              this.arr.shift()
            }

          })
        })
    }.width('100%').height('90%').backgroundColor(0xDCDCDC).padding({ top: 5 })

  }
}
