HarmonyOS 鸿蒙Next Tabs使用$$双向绑定索引，导致数据源在更新时索引重置为0

参考demo

@Entry

@Component

struct Second {

  @State tabs: Array<string> = []

  @State currentIndex: number = 0;

  private index = 0

  private tabsController: TabsController = new TabsController()

  build() {

    Column() {

      Button() {

        Text('Refresh')

          .fontSize(25)

          .fontWeight(FontWeight.Bold)

          .textAlign(TextAlign.Center)

      }

      .type(ButtonType.Capsule)

      .margin({

        top: 10

      })

      .backgroundColor('#0D9FFB')

      .width('40%')

      .height('5%')

      .onClick(() => {

        this.reloadTabs()

      })

      this.tabBuilder()

    }.width("100%")

  }

  @Builder tabBuilder2(index: number, name: string) {

    Column() {

      Text(name)

        .fontColor(this.currentIndex === index ? Color.Red : Color.Blue)

        .fontSize(16)

        .fontWeight(this.currentIndex === index ? 500 : 400)

        .lineHeight(22)

        .margin({ top: 17, bottom: 7 })

      Divider()

        .strokeWidth(2)

        .color('#007DFF')

        .opacity(this.currentIndex === index ? 1 : 0)

    }.width('100%')

  }

  @Builder

  tabBuilder() {

    Tabs({ controller: this.tabsController, index: $$this.currentIndex }) {

      ForEach(this.tabs, (item: string, index: number) => {

        TabContent() {

          Text(item).width('100%').height('100%')

        }.tabBar(this.tabBuilder2(index,item))

      }, (item:string) => item)

    }.width('100%')

    .height('100%')

    .barPosition(BarPosition.Start)

    .scrollable(false)

    .barMode(BarMode.Fixed)

    .barHeight(50)

    .expandSafeArea([SafeAreaType.SYSTEM], [SafeAreaEdge.TOP, SafeAreaEdge.BOTTOM])

    .onChange((index: number) => {

    })

    .onTabBarClick((index) => {

      this.currentIndex = index

    })

  }

  aboutToAppear(): void {

    this.reloadTabs()

  }

  reloadTabs() {

    this.tabs = []

    for (let index = 0; index < 5; index++) {

      this.tabs.push("Tab" + this.index + "-" + index)

    }

    this.index++

  }

}
