      }.active(this.active)

  }
}

interface NameObject {
  name: string;
}

class TextObject {
  text: NameObject;

  constructor(text: NameObject) {
    this.text = text;

}

// Detail.ets
import router from '@ohos.router'

@Entry
@Component
struct DetailExample {
  // 接收Navigator.ets的傳參
  params: Record< string, NameObject > = router.getParams() as Record< string, NameObject >
  @State name: NameObject = this.params.text

  build() {
    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Start, justifyContent: FlexAlign.SpaceBetween }) {
