Flutter安装SDK及配置

一、下载SDK

1.官网下载
https://docs.flutter.dev/development/tools/sdk/releases?tab=macos

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

3.通过brew命令下载
brew install --cask flutter

二、检查是否安装成功

flutter doctor

三、如果检查失败，检查环境变量并配置【配置完成之后，再执行flutter doctor，进行检查】

export FLUTTER_ROOT=你的flutter安装目录
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=$PATH:/你的flutter安装目录/bin

四、创建项目

flutter create 项目名称

创建完项目就可以，在lib下面编辑代码了
