HarmonyOS 针对tabBar的切换事件埋点监听

https://developer.huawei.com/consumer/cn/doc/best-practices-V5/bpta-application-track-practice-V5

在这个运维埋点统计最佳实践中，在tabBar做切换时，可以检测到willClick的回调，在外部无法拿到具体的组件做id和customPoperty的绑定，导致无法获取到具体的自定义信息，该如何处理？

可以尝试将tab和视图分开构造布局，在自定义tabBar上绑定id和customPoperty，参见以下demo：

import { DataResource } from '../common/DataResource';

@Entry
@Component
struct Index {
  private tabsController: TabsController = new TabsController()
  @State currentIndex: number = 0;

  onPageShow(): void {
    const uiContext: UIContext = this.getUIContext();
    console.log('text-1', JSON.stringify(uiContext.getFrameNodeById('text-1')?.getCustomProperty('text-1')));
  }

  @Builder
  TabBarBuilder(title: string, targetIndex: number) {
    Text(title)
      .fontWeight(targetIndex === this.currentIndex ? FontWeight.Bold : FontWeight.Normal)
      .padding(10)
      .id('text-' + (targetIndex + 1))//设置id
      .customProperty('text-' + (targetIndex + 1), DataResource['Index']['text-'+(targetIndex + 1)])//设置customProperty
      .onClick(() => {
        this.tabsController.changeIndex(targetIndex)
      })
  }

  build() {
    Row() {
      Column() {
        Flex({ direction: FlexDirection.Row }) {
          this.TabBarBuilder('页签1', 0)
          this.TabBarBuilder('页签2', 1)
        }

        Tabs({ barPosition: BarPosition.End, controller: this.tabsController }) {
          TabContent() {
            Text("页签1页面")
          }

          TabContent() {
            Text("页签2页面")
          }
        }
        .barHeight(0)
        .scrollable(false)
        .onChange((index: number) => {
          this.currentIndex = index;
        })
      }
    }
  }
}
