HarmonyOS给Navigation绑定PageMap是，如果PageMap定义的是全局的builder，运行时会crash

import { PageOne } from './Index' 
@Builder 
export function PageMap(name: string, param: object) { 
  if (name === 'pageOne') { 
    PageOne() 
  } 
} 
export class NavStackController { 
  stack : NavPathStack = new NavPathStack(); 
}
