调试时出现以下问题：

Error connecting to the service protocol: failed to connect to
http://127.0.0.1:56341/vQjFLT5wAX0=/

出现此问题是因为开启了代理，解决方法：

环境中配置本地地址不通过代理

export NO_PROXY=localhost,127.0.0.1

1、修改 $HOME/.zshrc文件

vim $HOME/.zshrc

2、添加以下内容

# Flutter路径
export PATH="$PATH:[Flutter路径]/flutter/bin"
# 国内镜像
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
# 代理
export HTTP_PROXY=http://127.0.0.1:1080
export HTTPS_PROXY=http://127.0.0.1:1080

3、刷新

source $HOME/.zshrc

4、检查Flutter信息

flutter doctor
