HarmonyOS 想在builder中插入builder

请参考以下文档：https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/quick-start/arkts-builderparam.md

并参考以下demo：

@Component
struct activeDialog {
  @Builder
  customBuilder() {
  }

  // 使用父组件@Builder装饰的方法初始化子组件@BuilderParam
  @BuilderParam customBuilderParam: () => void = this.customBuilder;

  build() {
    Column({ space: 5 }) {
      Text('9998888888')
      // this.customBuilderParam()
    }.width('100%').height('100%').justifyContent(FlexAlign.Center)
  }
}

@Entry
@Component
struct Parent {
  @State isShow: boolean = true
  @Builder
  componentBuilder() {
    Text(`Parent builder `)
  }

  build() {
    Column() {
      activeDialog({ customBuilderParam: this.componentBuilder })
    }
    .bindContentCover(this.isShow, this.componentBuilder(), {
      modalTransition: ModalTransition.NONE,
      // backgroundColor: 'rgba(0,0,0,0.5)',
      onAppear: () => {
        console.log("BindContentCover onAppear.")
      },
      onDisappear: () => {
        console.log("BindContentCover onDisappear.")
      }
    })
  }
}
