使用ForEach组件在点击后如何获得被点击的子组件的索引?

class FarmBean {
  name: string = ""
  fieldId: string = ""

  constructor(name, fieldId) {
    this.name = name
    this.fieldId = fieldId
  }
}

@Entry
@Component
struct test {
  @State FarmList: Array<FarmBean> = [
    new FarmBean('图片1.jpg', "id1"),
    new FarmBean('文本2.txt', "id2")
  ]

  build() {
    Column() {
      List() {
        ForEach(this.FarmList, (Farm: FarmBean, index: number) => {
          ListItem() {
            this.FarmListItem(Farm.name, Farm.fieldId)
          }
          .onClick(() => {
            console.info('====内容：', JSON.stringify(Farm), ",子组件在列表中的索引：" + index)
          })
        })
      }
      .listDirection(Axis.Vertical)
      .divider({
        strokeWidth: 1,
        startMargin: 60,
        endMargin: 10,
        color: '#a1949494' })
      .scrollBar(BarState.Auto)
    }
  }

  @Builder
  FarmListItem(name, fieldId) {
    Text('文件名' + name + ',文件id:' + fieldId).fontSize(20)
  }
}
