Mac 配置flutter
1.下载flutter的SDK，解压后放置随便路径
https://flutter.dev/docs/development/tools/sdk/releases?tab=macos
2.修改配置环境变量（路径为sdk解压后的放置路径）
vim ~/.bash_profile
//添加以下配置（/Users/mac/flutter是我的sdk解压路径）
export PATH=/Users/mac/flutter/bin:$PATH
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
:wq保存后 执行下 source ~/.bash_profile
3.检测环境
flutter -h 出现flutter帮助信息说明sdk安装配置成功
4.运行条件检测
flutter doctor 检测运行条件
一般需要依次运行以下命令：
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
brew update
brew install --HEAD usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
brew install ios-deploy
//如果brew update运行慢—————————————————————————
# 替换brew.git:
$ cd "$(brew --repo)"
# 中国科大:
$ git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
# 清华大学:
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
# 替换homebrew-core.git:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
# 中国科大:
$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
# 清华大学:
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
# 替换homebrew-bottles:
# 中国科大:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile
# 清华大学:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile
# 应用生效:

完成后flutter doctor应该是这样的

5 . 创建第一个flutter项目
cd 到项目文件夹后 使用flutter create xxxx_xxxx_xxx 即可 # 注意：项目名不能有大写字母！！！！！
6. 修改文件夹权限
sudo chmod -R 777 flutter_demo_01 //项目文件夹
sudo chmod -R 777 /Users/mac/flutter //sdk文件夹
7 .xcode 直接打开ios目录下的工程文件即可
8 .vscode 打开工程目录，运行flutter run即可。
R - 热更新
