Downloading CanvasKit failure error when running flutter on brower

Reason

此问题是由于国内无法直接访问 chrome-infra-packages.appspot.com， 导致安装包下载失败。更换全局代理后依旧无法正常安装启动，因此替换了 Flutter 的国内镜像源来解决此问题。

Solution

Windows

新增两个环境变量

• PUB_HOSTED_URL
  • https://pub.flutter-io.cn
• FLUTTER_STORAGE_BASE_URL
  • https://storage.flutter-io.cn

Linux

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
