HarmonyOS 连续两次@Link之后UI没更新

双向绑定的时候需要使用$进行值绑定操作从而驱动页面刷新。

import { ComponentB } from './ComponentB'
@Entry
@Component
export struct PageA{
  @State loginAgreement: boolean = true
  build() {
    Column() {
      ComponentB({
        // loginAccount: this.loginAccount,
        loginAgreementShow: true,
        loginAgreement: $loginAgreement
      })
    }}
}

import { ComponentC } from './ComponentC'
@Component
export struct ComponentB{
  @State loginAgreementShow: boolean = true
  @Link loginAgreement: boolean
  build() {
    ComponentC({
      selected:$loginAgreement
    })
  }
}
@Component
export struct ComponentC{
  @State loginAgreementShow: boolean = true
  @Link selected : boolean
  build() {
    Column() {
      Checkbox() {
        Text('sssssssssssssssssssssssssss').fontColor(Color.Red).fontSize(16).width('auto')
      }
      .onChange((value) => {
        this.selected = value
      })
      .select(this.selected )
    }}
}

另外Checkbox的select是从API version 10开始，该属性支持$$双向绑定变量的。
