flutter项目出现安卓环境的错，苹果运行没问题

我打印了gradel的错误信息大致意思是项目安卓目录的gradle不是由setting.gradel定义的，stackoverflow bing 百度都找过了还是解决不了。希望能给解答一下
打印完成以后如下：What went wrong:
Project directory '/Users/wenhuaren/Desktop/art/android/gradle' is not part of the build defined by settings file '/Users/wenhuaren/Desktop/art/android/settings.gradle'. If this is an unrelated build, it must have its own settings file.

试试修改项目下的build.gradle文件中下面这部分内容

allprojects {
    repositories {
        maven { url "https://storage.googleapis.com/download.flutter.io" }
        maven{ url 'https://maven.aliyun.com/repository/google'}
        maven{ url 'https://maven.aliyun.com/repository/jcenter'}
    }
}
