flutter 需要配置的几个环境变量

PUB_HOSTED_URL https://pub.flutter-io.cn //国内用户需要设置
FLUTTER_STORAGE_BASE_URL https://storage.flutter-io.cn //国内用户需要设置
ANDROID_HOME android SDK的安卓目录
PATH 添加 C:\flutter\bin以及Android需要的2个tools目录

mac配置环境变量：

vim ~/.bash_profile
输入：

export PATH=$PATH:~/flutter/bin:/Users/mac/Library/Android/sdk/platform-tools:/Users/mac/Library/Android/sdk/tools
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

保存完毕之后运行命令:
source ~/.bash_profile
然后就可以运行flutter命令了：
flutter --version
flutter channel
flutter build apk

解决方案：
