尝试在Flutter项目上添加Firebase时遇到错误

Question

每当添加实现'com.google.firebase：firebase-analytics：17.2.2'和应用插件：'com.google.gms.google-services'时，我都会收到错误消息进入app> build.gradle，以及 classpath'com.google.gms：google-services：4.3.3'进入android> build.gradle。 如果我不使用这三件事，则应用程序运行正常。我想念什么？

这是我遇到的错误

您需要迁移到androidx。检查这里：

https://flutter.dev/docs/development/androidx-migration

了解如何将应用程序迁移到androidX。

或者，您可以将flutter更新到最新版本，并创建一个将自动使用androidx的新项目。您可以通过执行以下命令进行更新：
