PersistentStorage持久化存储问题

index中  
@State isLogin: boolean | undefined = false  
PersistentStorage.persistProp('isLogin', false);  
this.isLogin = AppStorage.get<boolean>('isLogin')  
  
login中  
@StorageLink('isLogin') isLogin: boolean | undefined = false;  
Button .onClick(() => {  
  PersistentStorage.persistProp('isLogin', true)  
  AppStorage.setOrCreate('isLogin', true);  
  this.isLogin = AppStorage.get<boolean>('isLogin')  
})
