1、下载Flutter SDK

https://flutter.cn/docs/development/tools/sdk/releases

2、将文件解压到目录路径

cd /usr/local/

sudo unzip ~/Downloads/flutter_macos_1.17.5-stable.zip

3、配置Mac环境

export PATH=[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin:$PATH

配置flutter镜像地址

export PUB_HOSTED_URL=https://pub.flutter-io.cn

export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

[PATH_TO_FLUTTER_GIT_DIRECTORY]是安装目录

4、刷新环境配置数据

source $HOME/.bash_profile

注：在使用时发现，flutter环境配置后，重启终端需要重新刷新环境变量配置文件，来让flutter的配置生效。

5、查看Mac环境配置情况

echo $PATH

6、验证flutter是否配置成功

which flutter

7、Dart安装

brew tap dart-lang/dart

brew install dart

注：安装完成flutter，dart会默认安装在[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin/cache/dart-sdk中

8、Dart环境配置

export PATH=/Users/apple/.flutterDevelopment/flutter/bin/cache/dart-sdk/bin:$PATH

9、查看Dart版本

Dart —-version
