# Mac Flutter安装与配置 #

## 一、获取Flutter SDK ##

（1）官网下载适用的SDK：https://flutter.dev/docs/development/tools/sdk/releases?tab=macos\#macos  
（2）解压SDK安装包  
（3）配置环境变量  
命令行输入：`open .bash_profile`  
然后讲地址引用到文件中

export PATH=`你的flutter所在的文件夹路径`flutter/bin:$PATH

由于网络限制，建议把Flutter临时镜像加入，故完整代码应该是

#前两个是镜像地址，后面的`/flutter/bin:$PATH`是你clone的仓库地址，这里默认就是在你当前的系统路径中
    export PUB_HOSTED_URL=https://pub.flutter-io.cn
    export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
    export PATH=/Users/Talon/Desktop/Tools/flutterSdk/flutter/bin:$PATH

## 二、安装 ##

命令行中运行以下代码进行安装

flutter doctor

输出结果并没有成功

上面的信息可以看出

1.  flutter安装的版本
2.  Flutter运行所需的Android工具链，有些许可证没有接受
3.  XCode需要更新，IOS先跳过
4.  AS和IntelliJ 插件没有安装
5.  没有设备链接

解决：  
（1）接受许可

flutter doctor --android-licenses

一路输入 Y

（2）安装AS插件，安装完后重启AS。 注意 Flutter 和 Dart 两个插件都要安装！

并勾选 `File>Settings>Plugs>Android APK Support`，确认并重启AS

## 三、第一个flutter程序 ##

1.  选择File>New Flutter Project
2.  创建完成之后，启动即可。
