article 2025/1/3 4:25:53

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

在这里插入图片描述

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';
import { promptAction } from '@kit.ArkUI';

        .fontSize(24)
        .fontColor(Color.White)
        .fontWeight(FontWeight.Bold)
        .margin({ top: 10, left: 16 })

      Column() {
