Question

@Entry
@Component
struct Index {
  MSS: StyledString = new StyledString("MSSinit");

export struct Child {
  @Prop MSS: StyledString;
  private controller: TextController = new TextController();

  aboutToAppear(): void {
    console.info("this.MSS is " + this.MSS.getString());
  }
  build() {
    Text("123", { controller: this.controller })

  }
}

参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-universal-styled-string-V5\#规则说明StyledString不支持@State修饰，故也不支持@Prop修饰，在传递给子组件时会丢失数据
