Mac系统flutter环境搭建

Flutter中文官网

flutter 用这个

1、homebrew安装

-安装 homebrew，已安装跳过
-打开终端分别输入以下命令行

brew update
brew install --HEAD libimobiledevice
brew install ideviceinstaller ios-deploy cocoapods
pod setup

2、下载flutter SDK

可直接clone，也可去官网下载后放入根目录，但是我去下载了解压后放入根目录不行，所以还是说直接clone的方式吧，打开命令行

cd ~
git clone -b stable https://github.com/flutter/flutter.git

这个只能取决于网速了，下载完成后

3、配置环境镜像

这一步必须查看文章顶部的flutter文档，文档明确指出：此镜像为临时镜像，并不能保证一直可用，读者可以参考详情请参考 Using Flutter in China 以获得有关镜像服务器的最新动态。
-跳转根目录

cd ~

-打开隐藏文件.bash_profile

vim ~/.bash_profile

-将文档中最新的镜像和路径加进去，路径自行修改，我目前的操作是放在根目录的，/Users/luohao是我的根目录

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=/Users/luohao/flutter/bin:$PATH  

source ~/.bash_profile

-验证环境是否成功

flutter -h

无报错则成功，成功的最后大概是这样的

Run "flutter help <command>" for more information about a command.
Run "flutter help -v" for verbose help output, including less commonly used options.

4、配置android studio完全可按照文档提示操作

5、检查flutter环境

flutter doctor

将有叉的地方全部处理掉，命令行会给出相应提示

5、处理完后再次检查，成功后是这样的

luohaos-MacBook-Pro:~ luohao$ flutter doctor
