一、下載
1、下載Flutter，在命令行：git clone -b beta?https://github.com/flutter/flutter.git
或者可以手動下載Flutter，并放入想放的文件位置，如果是從GitHub自己下載的Flutter，可能會沒有.git文件，需要手動創(chuàng)建：git init
二、配置文件.bash_profile
open ~/.bash_profile，如沒有創(chuàng)建：touch .bash_profile
添加如下：
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=[你的flutter文件路徑]/bin:$PATH
三、執(zhí)行flutter doctor
