下面开始正题：

安装Flutter

• 1、下载 Flutter SDK，必须用 git clone，方便安装依赖。

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

  假设其存放的绝对路径为 A；

• 2、设置 flutter 命令全局有效（注意：如果使用了 zsh，终端启动时 ~/.bash_profile 将不会被加载，解决办法：修改 ~/.zshrc文件，在其中添加：source ~/.bash_profile）

  • a. 在 HOME 目录下创建 .bash_profile文件

    touch ~/.bash_profile
    

  • b. 配置 .bash_profile 信息，需要特别注意的是：最后一个命令里的 A就是 Flutter SDK 在你电脑里的绝对路径。

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

  • c. 保存后，执行

    source ~/.bash_profile
    

• 3、安装flutter依赖

  flutter doctor
  

创建和运行工程

• 1、创建一个新工程

flutter create my_app

• 2、运行

cd my_app
flutter run

FAQ：

• 1、运行iOS模拟器报错：ERROR: Could not connect to lockdownd, error code -17
  解决：

brew install --HEAD libimobiledevice -g
brew install ideviceinstaller -g
sudo chmod -R 777 /var/db/lockdown

拓展
配置AndroidStudio 的 adb：
打开~/.bash_profile，添加以下代码：

ANDROID_HOME=~/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

保存后，执行

source ~/.bash_profile
