如何实现根据服务端下发的配置动态加载tab页面？

//OtherPage页面  
import router from '@ohos.router'  
  
@Entry  
@Component  
struct OtherPage {  
  
  build() {  
    Row() {  
      Column() {  
        Button("去首页")  
          .fontSize(50)  
          .fontWeight(FontWeight.Bold)  
          .onClick(()=>{  
            AppStorage.setOrCreate("IndexPage", 0)  
            router.pushUrl({url:'pages/MainPage'})  
          })  
  
        Button("去第二页")  
          .fontSize(50)  
          .fontWeight(FontWeight.Bold)  
          .onClick(()=>{  
            AppStorage.setOrCreate("IndexPage", 1);  
            router.pushUrl({url:'pages/MainPage'})  
          })  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}  
  
//MainPage页面  
@Entry  
@Component  
struct MainPage {  
  @StorageLink("IndexPage") currentIndex: number = 0  
  private controller: TabsController = new TabsController()  
  
  @Builder  
  tabBuilder(index: number, name: string) {  
    Column() {  
      Text(name).fontSize(22)  
      Divider()  
        .strokeWidth(2)  
        .color('#007DFF')  
        .opacity(this.currentIndex === index ? 1 : 0)  
    }  
  }  
  
  build() {  
    Tabs({ barPosition: BarPosition.End, index:this.currentIndex,controller:this.controller}) {  
  
      TabContent() {  
      }  
      .backgroundColor(Color.Yellow)  
      .tabBar(this.tabBuilder(0, 'yellow'))  
  
      TabContent() {  
      }  
      .backgroundColor(Color.Green)  
      .tabBar(this.tabBuilder(1, 'green'))  
  
  
    }  
    .onChange((index: number) => {  
      this.currentIndex = index  
    })  
  }  
}
