我使用fluwx组件在鸿蒙手机上跳转微信小程序，未打开目标小程序，打开了“演示”小程序。在使用微信SDK跳转微信小程序之前，SDK已经初始化并注册appid。

fluwx组件版本：

fluwx:
  dependency: "direct main"
  description:
    name: fluwx
    sha256: "7e92d2000ee49c5262a88c51ea2d22b91a753d5b29df27cc264bb0a115d65373"
    url: "https://pub.dev"
  source: hosted
  version: "5.7.5"

鸿蒙原生端使用的微信SDK版本：

"overrides": {
  "@tencent/wechat_open_sdk": "^1.0.16"
}

fluwx源码：

// 注册APPID
case "registerApp":
  hilog.info(DOMAIN, TAG, `[registerApp] - appId: ${call.argument("appId")};iOS: ${call.argument("iOS")};android: ${call.argument("android")};universalLink: ${call.argument("universalLink")};`)
  WXAPiHandler.registerApp(call, result);
  hilog.info(DOMAIN, TAG, `[registerApp] - register app finished, registered is ${WXAPiHandler.wxApiRegistered}`)
  break;
