HarmonyOS LocalStorage在Navgation内的使用？

Question

我们某个页面，之前是自己绑定一个LocalStorage，每次进这个页面LocalStorage都是重新new一次

现在改成Navigation之后LocalStorage不会重新new了，导致数据出问题，请问Navigation的情况下，各个页面因为不再是@Entry了，如何保证每次跳这个页面一次都绑定一个新的LocalStorage呢？

试了下面这样写可以,但是LocalNavDemo拿不到传进去这个LocalStorage，用this.getUIContext().getSharedLocalStorage()拿出来是空，请问这种方式传进去的LocalStorage如何拿到？

function initStorage():LocalStorage{
  let storage = new LocalStorage()
  storage.setOrCreate("KEY",Math.random()*1000)
  return storage
}
@Builder
export function LocalNavDemoBuilder(){
  LocalNavDemo({},initStorage())
}


@Component
export struct LocalNavDemo{

  @LocalStorageProp("KEY") localKey:number = 0
  @Consume pageStack: NavPathStack
  aboutToAppear(): void {
    let storage = this.getUIContext().getSharedLocalStorage()
    let key = storage?.get("KEY") as number
    console.log(key?.toString())
  }
  build() {
    NavDestination(){
      Text(`key:${this.localKey}`)
    }
  }
}

通过构造函数传递LocalStorage不能拿到实例, 可以创建全局map存LocalStorage, 再在对应的页面获取使用
