Question

android studio安装flutter插件后新建项目，运行时超时，已更换阿里云镜像
再次运行时遇见异常：

* Error running Gradle:

If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to C:\Users\Administrator\AppData\Local\Android\Sdk\ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

Please review your Gradle project setup in the android/ folder.

网上找了也没有遇上合适的答案来解决它，我看到提示import com.android.builder.model.AndroidProject是这个包的问题，请问该如何解决
请各位大佬指点

Answer 1

已解决：
只在build.gradle文件中更换阿里云镜像，在flutter sdk下还是使用flutter下载的配置（之前改过），就可以了

Answer 2

你用命令行试试,flutter create my-app

Answer 3

最终解决了没，我这之前还正常跑的。
