1、下载flutter

存放位置：

/Users/zhangchaozhou/Documents/flutter

2、配置环境

打开配置文件：

vi ~/.bash_profile

编辑保存配置文件：

export M2_HOME=/Users/zhangchaozhou/Documents/bin/apache-maven-3.5.0
export PATH=$PATH:$M2_HOME/bin
export PATH=${PATH}:/Users/zhangchaozhou/Documents/flutter/bin

执行命令：

source ~/.bash_profile

否则执行flutter命令会出现以下错误：

-bash: flutter: command not found

3、发布插件库到pub

在Android Studio终端执行命令：

flutter packages pub publish --dry-run

出现警告：

Missing requirements:
* Your pubspec.yaml must have an "author" or "authors" field.
* Your pubspec.yaml is missing a "homepage" field.

添加配置：

author: chaozhouzhang <13760289294@139.com>
homepage: https://github.com/chaozhouzhang

检查成功：

Package has 0 warnings.

发布命令：

flutter packages pub publish --server=https://pub.dartlang.org
