最近想继续玩下Flutter，发现pub.dev居然被封锁了，试了下网上的方案，都不可行，尝试组合了一下，用下面的方案解决了。
第一步：
找到这个文件
D:\flutter\packages\flutter_tools\lib\src\http_host_validator.dart
把下面的地址修改为：
const String kPubDev = 'https://pub-web.flutter-io.cn/'; 第二步： 设置系统变量name: PUB_HOSTED_URL;
value: https://pub-web.flutter-io.cn
name: FLUTTER_STORAGE_BASE_URL;
value: https://storage.flutter-io.cn
运行flutter pub get 结果：
(base) PS D:\Project\Flutter\globaluniversity> flutter pub get
