今天在尝试使用Flutter 的时候，需要使用一个第三方库
修改了 pubspec 文件之后，AS 像往常一样提示 需要 package get.
之前都挺正常，不知道今天怎么了。
一直处在
Running "flutter packages get" in project_name...
的状态。
没关系我等，等了大概有10分钟吧，看了下 logcat
OS Error: 信号灯超时时间已到
, errno = 121, address = storage.googleapis.com, port = 60109
pub get failed (69) -- attempting retry 2 in 2 seconds...

看来，应该是 storage.googleapis.com 撞墙了。
大概意思就是 把默认的 package 获取地址改为访问没有问题的镜像站就可以了。
具体操作
- Linux 或 Mac
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
- Windows
新增两个环境变量即可
PUB_HOSTED_URL ===== https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL ===== https://storage.flutter-io.cn
执行一下 flutter doctor命令
下载在 package get 应该就没有问题了。
反正我是没问题了。
