【Flutter开发技巧】Error connecting to the service protocol: failed to connect

Error connecting to the service protocol: failed to connect to http://127.0.0.1:56341/pzVveLr8I8w=/

问题剖析：

由于开启了代理导致dartvm启动出现问题，flutter一启动就白屏闪退

➜  flutter git:(stable) ✗ flutter doctor

解决办法

在环境中，设置export NO_PROXY=localhost,127.0.0.1

然后在终端中：flutter doctor
