Answer 1

ForEach(this.pushNews, (item: PushNewsBean) => {
          if (item.Type == 1) {
            this.TestComponent({ pushNews: item, newsType: this.newsType })
          } else {
            this.TestComponent({ pushNews: item, newsType: this.newsType })
          }
        }, (item: PushNewsBean, index: number) => `${item?.Type}-${index}`)

 @Builder
  TestComponent(item: PushNewsPrams) {
    Text(item?.pushNews?.SharCount)
  }
class PushNewsPrams {
  pushNews: Partial<PushNewsBean> = {}
  newsType: number = 0
}
