Error connecting to the service protocol: HttpException: Connection closed before full header was received, uri = http://127.0.0.1:54153/ws

个人是Windows Android Studio

首先排查基本错误：查看自己Studio 的 File => Settings | Languages & Frameworks => Flutter SDK Path是否对。

错误可能性1：下载的是别人的项目，而你们的flutter环境并不一样造成的，建议查看他当时的Flutter SDK 版本，将我们的替换成他的版本，或者不知道他版本的话，请移步FlutterSDK官网https://flutter.io/sdk-archive/#windows直接下载Stable channel最新版解压打开目录找到flutter_console.bat 打开输入flutter doctor 看看有无错误然后再去环境变量的Path中修改SDK目录再将Studio的flutterSdk路径改成最新的重启Studio即可

错误可能性2：可能设置了代理，需要修改代理

错误可能性3：地址链接自查 https://github.com/flutter/flutter/issues/6724
