HarmonyOS NEXT 实战之元服务：静态案例效果---咖啡制作实况窗

背景：

前几篇学习了元服务，后面几期就让我们开发简单的元服务吧，里面丰富的内容大家自己加，本期案例 仅供参考

先上本期效果图 ，里面图片自行替换

效果图1完整代码案例如下：

import { authentication } from '@kit.AccountKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { hilog } from '@kit.PerformanceAnalysisKit';

@Entry
@ComponentV2
struct Index {


  build() {
    Column() {


      Column() {
        Row() {
          Row() {
