记录Flutter开发环境搭建踩过的坑-初次运行卡在Running Gradle task 'assembleDebug' 解决方法
flutter安装目录下，把
/packages/flutter_tools/gradle/flutter.gradle中的private static final String MAVEN_REPO = "https://storage.googleapis.com/download.flutter.io";改为private static final String MAVEN_REPO = "https://mirrors.tuna.tsinghua.edu.cn/flutter/download.flutter.io";修改后保存，重新运行app，等待一点时间，跑起来了，ok!
