Flutter环境搭建(Mac)

.从github拉取代码：

  git clone -b beta https://github.com/flutter/flutter.git

配置环境变量：

  在当期用户目录下创建.bash_profile文件，如果该文件已经存在，	则直接打开。将以下代码复制到.bash_profile中，
  export PATH_TO_FLUTTER_GIT_DIRECTORY=/Users/你的用户名/flutterexport PATH=${PATH}:${PATH_TO_FLUTTER_GIT_DIRECTORY}/bin
  完成之后点击保存，在命令行中执行source  .bash_profile，然后输入flutter 进行测试。没有出现commond not found即是配置成功。

执行命令flutter doctor ，命令的作用是检测还需要安装的依赖。

 [✓]Flutter(Channel beta,v0.1.5,on Mac OS X 10.13.3 17D102,locale zh-Hans-CN)
 [✓]Android toolchain - develop for Android devices(Android SDK 27.0.3)

所有的依赖安装完成以后 会有如下的提示

  Doctor summary (to see all details, run flutter doctor -v):

这个时候的 你的环境配置就算是完成了。(因为本人之前是做ReactNtive开发的，所以已经安装好了一些其他的环境，例如AndroidStudio，Xcode等)
