// 建议通过在ParentComp上添加@Preview，预览ParentComp来查看ChildComp的预览效果
@Preview //组件预览
@Component
struct ParentComp {
装饰的变量reviewVotes由入口组件ParentComp提供其后代组件
  @Provide reviewVotes: number = 10;

  build() {
    Column() {
      Button(`reviewVotes(${this.reviewVotes}), give +1`)
        .onClick(() => this.reviewVotes += 1)
      ChildComp()
    }
  }
}

// @Preview 不建议直接预览ChildComp
@Component
struct ChildComp {
装饰的变量通过相同的属性名绑定其祖先组件ParentComp内的@Provide装饰的变量
  @Consume reviewVotes: number;
  build() {
    Column() {
      Text(`reviewVotes(${this.reviewVotes})`)
      Button(`reviewVotes(${this.reviewVotes}), give +1`)
        .onClick(() => this.reviewVotes += 1)
