HarmonyOS 鸿蒙Next wrappedBuilder navdestination 数据同步问题

可以参考这段代码：

let globalBuilder: WrappedBuilder<[ListData]> = wrapBuilder(myBuilder);
@Observed
export class IntArray extends Array<number> {
}

@Observed
class ListData {
  // new运算符使得@Observed生效，@Observed观察到IntArray的属性变化。
  list: IntArray = new IntArray()
  record_date:string = '1111'
}

@Entry
@Component
struct GridPage {
  @State listData: ListData = new ListData();
  @State num: number = 0;
  build() {
    Column() {
      Text(this.listData.record_date)
      Button('点击加载更多')
        .onClick(() => {
          this.num++;
          this.listData.list.push(this.num)
        })
      globalBuilder.builder(this.listData)
    }
    .width('100%')
    .height('100%')
    .margin({ top: 5 })
    .backgroundColor(Color.White)
  }
}

@Builder
function myBuilder($$:ListData){
  ListDataView({list:$$.list})
}

@Component
struct ListDataView{
  @ObjectLink list: IntArray
  scroller: Scroller = new Scroller()
  build() {
    Grid(this.scroller) {
      ForEach(this.list, (item: number) => {
        GridItem() {
          Column({ space: 5 }) {
            Image('')
              .width(50).height(50)
              .backgroundColor(Color.Blue)
            Text(item.toString())
              .fontSize(12)
              .fontColor(0x25292e)
          }
          .padding(5)
          .alignItems(HorizontalAlign.Center)
          .width('100%')
          .aspectRatio(1)
          .backgroundColor("#FF3333")
        }
      },(item:number)=>JSON.stringify(item))
    }
    .layoutWeight(1)
    .columnsTemplate('1fr 1fr')
    .columnsGap(1)
    .rowsGap(1)
    .width('90%')
    .backgroundColor(Color.Gray)
  }
}

@Component
struct customGridItem {
  build() {
    Column({ space: 5 }) {
      Image($r('app.media.test'))
        .width(50).height(50)
        .backgroundColor(Color.Red)
      Text("相册")
        .fontSize(12)
        .fontColor(0x25292e)
    }
    .padding(5)
    .alignItems(HorizontalAlign.Center)
    .width('100%')
    .aspectRatio(1)
    .backgroundColor("#FF3333")
  }
}
