flutter项目编译问题汇总
1、kotlin compiler embeddable下载慢的解决办法
备注：可以使用https://developer.aliyun.com/mvn/search这个链接搜索并下载
2、运行Flutter项目一直卡在--Running Gradle task 'assembleDebug'
解决方法：
第一步：修改flutter安装目录/packages/flutter_tools/gradle文件夹中的两个文件flutter.gradle、resolve_dependencies.gradle，修改内容如下图
private static final String DEFAULT_MAVEN_HOST = "https://storage.flutter-io.cn";
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'https://maven.aliyun.com/repository/public' }
String storageUrl = System.getenv('FLUTTER_STORAGE_BASE_URL') ?: "https://storage.flutter-io.cn"
第二步：修改项目中Android的gradle配置，android\build.gradle，将
google()
jcenter()
改成
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'https://maven.aliyun.com/repository/public' }
备注：https://developer.aliyun.com/mvn/guide 阿里云仓库服务
