flutter开发的一个小小小问题，内网依赖下不来

问题

由于众所周知的原因，flutter编译时，经常出现Could not get resource ' storage.googleapis /download.flutter.io…'的问题，如下：

* What went wrong: Could not determine the dependencies of task ':app:lintVitalRelease'. > Could not resolve all artifacts for configuration ':app:debugCompileClasspath'. > Could not download armeabi_v7a_debug-1.0.0-cdbeda788a293fa29665dc3fa3d6e63bd221cb0d.jar (io.flutter:armeabi_v7a_debug:1.0.0-cdbeda788a293fa29665dc3fa3d6e63bd221cb0d) > Could not get resource ' storage.googleapis /download.flutter.io/io/flutter/armeabi_v7a_debug/1.0.0-cdbeda788a293fa29665dc3fa3d6e63bd221cb0d/armeabi_v7a_debug-1.0.0-cdbeda788a293fa2966 5dc3fa3d6e63bd221cb0d.jar'. > Could not GET ' storage.googleapis /download.flutter.io/io/flutter/armeabi_v7a_debug/1.0.0-cdbeda788a293fa29665dc3fa3d6e63bd221cb0d/armeabi_v7a_debug-1.0.0-cdbeda788a293fa29665dc3fa 3d6e63bd221cb0d.jar'. > Connection reset * Try: Run with --stacktrace option to get the stack trace.

修改flutter中gradle的仓库配置，目录为：D:\google\flutter\packages\flutter_tools\gradle 打开flutter.gradle，然后修改仓库信息为：http://mirror.nju.edu /flutter，如下：

// private static final String DEFAULT_MAVEN_HOST = " storage.googleapis "; private static final String DEFAULT_MAVEN_HOST = "http://mirror.nju.edu /flutter"; 分析

然后，我又看了下flutter.gradle里面的代码，给大家看看：

// Configure the Maven repository. String hostedRepository = System.env.FLUTTER_STORAGE_BASE_URL ?: DEFAULT_MAVEN_HOST String repository = useLocalEngine() ? project.property('local-engine-repo') : "$hostedRepository/download.flutter.io" rootProject.allprojects { repositories { maven { url repository } } }

真是自作孽不可活，明明有FLUTTER_STORAGE_BASE_URL这个环境变量可以去设置，自己懒不设置，活该！

快捷

跟我一样懒惰的兄弟们，给你们把链接奉上， docs.flutter.dev/community/china 自取，去设置环境变量，别懒得一坨耙耙一样了！！！
