## 项目简介

1. 基于flutter和[tun2socks](https://github.com/xjasonlyu/tun2socks)开发.
2. [appproxy](https://github.com/ys1231/appproxy) 是一个轻量级的VPN代理工具，支持HTTP, SOCKS5协议
2. [appproxy](https://github.com/ys1231/appproxy) 是一个轻量级的VPN代理工具，支持HTTP, SOCKS5协议.
3. 功能单只做代理,可分app代理, **_双击修改配置_** 逻辑比较简单, 主打一个能用就行.
4. 出于学习熟悉flutter的目的去做的,分享给大家,顺便帮我测试一下.
5. 加上[MoveCertificate](https://github.com/ys1231/MoveCertificate) 上下游都有了哈哈.
