怎样将LocalStorage实例从UIAbility共享到一个或多个视图？

import { UIAbility } from '@kit.AbilityKit';
import { window } from '@kit.ArkUI';

export default class EntryAbility extends UIAbility {
para:Record<string, number> = { 'PropA': 47 };
storage: LocalStorage = new LocalStorage(this.para);

onWindowStageCreate(windowStage: window.WindowStage) {
windowStage.loadContent('pages/Index', this.storage);
}
}
