0x02、JDK 安装：
由于官网下载比较缓慢。可以下载我百度网盘的JDK：链接: https://pan.baidu.com/s/1ibnt4PnJgOwFjxNdI3l47Q 提取码: v2jj 复制这段内容后打开百度网盘手机App，操作更方便哦；

Mac下如何安装JDK：详细过程可以参考：https://www.cnblogs.com/quickcodes/p/5127101.html
安装好JDK后需要配置JDK的环境变量：请参考：Mac下如何配置环境变量
0x03、Flutter JDK 安装：
由于官网下载比较缓慢。可以下载我百度网盘的Flutter SDK：https://pan.baidu.com/s/1OQLCy44KBbd1IoBuUzz1eQ

我的 Flutter 安装在了如下路径（home目录下载新建一个app文件夹中）

配置环境变量:
-
在终端执行
opne ~/.bash_profile，加入Flutter的安装路径-
export PATH=/Users/mingo/app/flutter/bin:$PATH
image 保存关闭 执行：
source ~/.bash_profile
-

这个时候应该能运行flutter命令了，我们运行命令行：
flutter -h- 出现如下：
$ flutter -h
