1，下载git clone
https://github.com/flutter/flutter.git
2，flutter doctor
问题：-bash: fultter: command not found
解决：
export PATH=/Users/对应资源位置/flutter/bin:$PATH
3 更新环境变量
文档上标明的： export PATH=pwd/flutter/bin:$PATH
可以使用但是只是暂时针对当前命令行窗口，要想是永久使用则需要更新环境变量则需要编辑profile.
vim ~/.bash_profile then
export PATH=$PATH:/Users/liuheng/flutterDev/flutter/bin
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
source ~/.bashrc
最后重新打开iterm
4，iOS相关配置
问题1：Verify that all connected devices have been paired with this computer in Xcode
解决：根据终端提示即可
brew update
brew uninstall --ignore-dependencies libimobiledevice
brew uninstall --ignore-dependencies usbmuxd
brew install --HEAD usbmuxd
brew unlink usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
问题2：RPC failed; curl 18 transfer closed with outstanding read data remaining 项目太极没有更新，tag资源文件太大超时了。
解决：
git config --global http.postBuffer 524288000
可惜并没解决，尝试使用官方镜像下载（之前我是打开vpn）
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
5，android配置
问题1：
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
解决：
在plugin中搜索flutter并安装。关闭后重新打开android studio即可。
可以看得出自己人有多好说话。。。
问题2：
Dart SDK is not Configured
解决:
1,打开Preferences->Languages&Frameworks->Flutter->设置Flutter SDK Path为Flutter文件夹路径
2,打开Preferences->Languages&Frameworks->Dart->选中Enable->./bin/cache/dart-sdk
