HarmonyOS Tabs 组件如何在尾部添加一个 image 组件

请参考以下demo:

@Entry
@Component
struct Index {
  @State tabArray: Array<number> = [0, 1, 2, 3, 4, 5, 6]
  private controller: TabsController = new TabsController()
  @State currentIndex: number = 0
  @State indicatorLeftMargin: number = 0
  @State indicatorWidth: number = 0

  @Builder
  Tab(tabName: string, tabItem: number, tabIndex: number) {
    Row({ space: 20 }) {
      Text(tabName).fontSize(18)
        .fontColor(tabItem === this.currentIndex ? Color.Red : Color.Black)
        .id(tabIndex.toString())
        .onAreaChange((oldValue: Area, newValue: Area) => {
          if (this.currentIndex === tabIndex && (this.indicatorLeftMargin === 0 || this.indicatorWidth === 0)) {
            if (newValue.position.x != undefined) {
              let positionX = Number.parseFloat(newValue.position.x.toString())
              this.indicatorLeftMargin = Number.isNaN(positionX) ? 0 : positionX
            }
            let width = Number.parseFloat(newValue.width.toString())
            this.indicatorWidth = Number.isNaN(width) ? 0 : width
          }
        })
    }
    .justifyContent(FlexAlign.Center)
    .constraintSize({ minWidth: 35 })
    .width(80)
    .height(35)
    .borderRadius({ topLeft: 10, topRight: 10 })
    .onClick(() => {
      this.controller.changeIndex(tabIndex)
      this.currentIndex = tabIndex
    })
  }

  build() {
    Column() {
      // 页签
      // Stack({ alignContent: Alignment.TopStart }) {
      Flex() {
        Scroll() {
          Row() {
            ForEach(this.tabArray, (item: number, index: number) => {
              this.Tab("页签 " + item, item, index)
            })
          }
          .justifyContent(FlexAlign.Start)
        }
        .align(Alignment.Start)
        .scrollable(ScrollDirection.Horizontal)
        .scrollBar(BarState.Off)
        .width('100%')

        Image($r('app.media.startIcon'))
          .width(60)
          .height(50)
          .borderRadius(5)
          .padding({ left: 5, bottom: 2 })
      }
      .width('100%')
    }
  }
}
