0x01-2、2-1 Flutter开发环境的安装-02：
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
-
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

0x04-4、解决 iOS 环境
按照如下截图，依次一个个执行如图命令。
第六个命令 brew install ios-deploy 安装完如下:

因为不需要使用 IntelliJ IDEA来开发，如果你电脑中没有安装IntelliJ IDEA是不会提示这个警告的，所以可以先不管这个栏目的❗️和 ❌
到此，Flutter 环境搭建完成，可以用 Android Studio，新建第一个 Flutter项目了。
