flutter doctor报网络错误
[!] Network resources
    X A cryptographic error occurred while checking "https://maven.google.com/": Connection terminated during handshake
      You may be experiencing a man-in-the-middle attack, your network may be compromised, or you may have malware

解决步骤：

打开/path-to-flutter-sdk/packages/flutter_tools/lib/src/http_host_validator.dart文件
修改https://maven.google.com/为 google maven 的国内镜像
如https://maven.aliyun.com/repository/google/
删除/path-to-flutter-sdk/bin/cache 文件夹
重新执行flutter doctor
