HarmonyOS Navigtion组件，两个NavDestination之间如何同步状态变量

let para: Record<string, number> = { 'PropA': 1 };  
let storage: LocalStorage = new LocalStorage(para);  
  
@Entry(storage)  
@Component  
struct Index {  
  @State message: string = 'Hello World';  
  @LocalStorageLink('PropA') linkNumber: number = 1;  
  @Provide pageInfo: NavPathStack = new NavPathStack()  
  
  @Builder  
  pageMap(name: string) {  
    if (name === 'page1') {  
      Page1()  
    } else if (name === 'page2') {  
      Page2()  
    }  
  }  
  
  build() {  
    Navigation(this.pageInfo) {  
      Text(this.linkNumber.toString()).onClick(() => {  
        this.linkNumber++;  
      })  
      Button('to page1').onClick(() => {  
        this.pageInfo.pushPathByName('page1', null)  
      })  
    }  
    .navDestination(this.pageMap)  
  }  
}  
  
  
@Component  
struct Page1 {  
  @Consume pageInfo: NavPathStack  
  @LocalStorageLink('PropA') childLinkNumber: number = 1;  
  
  build() {  
    NavDestination() {  
      Column() {  
        Text(this.childLinkNumber.toString()).onClick(() => {  
          this.childLinkNumber++  
        })  
        Button('to page2').onClick(() => {  
          this.pageInfo.pushPathByName('page2', null)  
        })  
      }  
    }  
  }  
}  
  
@Component  
struct Page2 {  
  @LocalStorageLink('PropA') childLinkNumber: number = 1;  
  
  build() {  
    NavDestination() {  
      Column() {  
        Text(this.childLinkNumber.toString()).onClick(() => {  
          this.childLinkNumber++  
        })  
      }  
    }  
  }  
}
