安装之前的环境：
pod: 1.5.3
xcode : 10.1
1. 获取Flutter SDK
通过官网地址：https://flutter.io/sdk-archive/#windows 下载最新的SDK
2. 配置环境变量
进入文件.bash_profile ，如果没有就通过命令创建一个 touch .bash_profile
xia:~ mac$ vim .bash_profile
在文件中加入一行
export PATH={pwd}/flutter/bin:$PATH
其中pwd是下载的flutter所在的文件路径
例如，我的flutter下载之后放在了~/flutter路径下，那么我的就是
export PATH=~/flutter/bin:$PATH
接下来运行source命令，更新配置
xia:~ mac$ source .bash_profile
3. 运行Flutter
执行命令
xia:~ mac$ flutter -h
应该会出现' Welcome to Flutter! '的欢迎语，具体命令输出就不粘贴了
4. 检查Flutter环境
执行命令flutter doctor
xia:~ mac$ flutter doctor
此时我的窗口出现了下面的输出，显示[✗][!]就是错误和警告的地方，接下来按照提示一步一步解决

If Android SDK has been installed to a custom location, set ANDROID_HOME
to that location.
You may also want to add it to your PATH environment variable.

1. 安装Android Studio、Android SDK、Flutter插件、Dark插件
此时并未安装Android SDK。第一步安装Android Studio之后，启动，会弹出一个框，点击cancel，接下来Android Studio会自动安装SDK。安装好了之后，重启Android Studio，在Android Studio-Preference-Plugins中安装Fluuter和Dark插件
再次执行 flutter doctor 命令

安装了Flutter和Dark插件，还是报下边的错误
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
我的解决办法是执行了一下
flutter doctor -v
报✗ Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses错误的话就执行一下
flutter doctor --android-licenses就好,确认一下协议，输入y确认下就行
2. 安装iOS toolchain
这个比较简单，按照提示步骤一步一步来
[!] iOS toolchain - develop for iOS devices (Xcode 10.1)
✗ libimobiledevice and ideviceinstaller are not installed. To install with
Brew, run:
brew update
brew install --HEAD usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
在这个过程中我安装libimobiledevice的时候报了下边这个错误,解决办法是执行 pod setup，然后多试几次，多试几次！！！
Cloning into '/Users/mac/Library/Caches/Homebrew/libimobiledevice--git'...
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
最后再执行 flutter doctor 输出以下信息，说明全部安装完毕，恭喜~
