firebase - 尝试在Flutter项目上添加Firebase时遇到错误

Question

每当将实现'com.google.firebase:firebase-analytics:17.2.2'和应用插件:'com.google.gms.google-services'与app> build.gradle一起添加时，我都会收到错误消息类路径'com.google.gms:google-services:4.3.3'放入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？

这是我得到的错误

另外，为什么这东西总是红色。 app> build.gradle

您需要迁移到androidx。在这里检查:

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:

flutter upgrade
