为什么Deep Link Web URL查询为空

Question

使用Flutter和Firebase动态链接，我可以创建一个链接。当它被点击时，它会打开应用程序，但没有链接数据，也不会触发任何链接被点击的回调。相反，在Xcode日志中，我得到Notes是从应用程序复制到Deep Link Web URL query is empty中，然后单击。我是否遗漏了什么，或者我还可以检查什么来使其正常工作？

Firebase Deep Link Web URL query is empty - iOS查看了这篇相关文章，但安装所需的pod依赖项不是解决方案，正如您可以在下面的pod安装日志中看到的那样。

Answer 1

解决我的问题的解决方案是在initDynamicLinks()中调用await FirebaseDynamicLinks.instance.getInitialLink();，同样的错误仍然出现在Xcode日志中，但我能够解析出链接数据。
