// Example for package:flutter_sangfor_easy_connect.
//
// Run with `dart run` after configuring a reachable EasyConnect
// deployment. The connector performs the XML login, conf parsing, minimal
// TLS data-channel bring-up, Query-IP, and RX/TX streams, then dials one
// TCP connection over the userspace TCP-over-L3 proxy.
//
// For a userspace SOCKS5 frontend instead of per-connection dials, see
// the root package's `SangforSocks5Server`.
