无法解析com.google.gms:google服务:4.3.3

Question

在从github存储库克隆项目后，我安装了最新版本的android和flutter，得到了这个错误

正在调试模式下在BKK LX2上启动lib\main.art。。。

libmain.dart
AILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project 'android'.

只有在从github和bitbucket克隆任何项目时，如果创建新项目工作正常，才会出现此错误。

此外，在flutter医生的结果中也存在问题，可以很好地处理android工作室和visualstudio代码中的is问题。

谢谢你帮我。

您需要先安装flutter和dart，然后转到android工作室进行配置选择更新更新你的版本，然后去配置agian选择插件搜索flutter，dart并安装它们，然后重新启动
