Flutter基于Mac的环境配置
1、下载Flutter SDK
git clone https://github.com/flutter/flutter.git
2、配置Flutter镜像+Flutter环境变量
( 先创建.bash_profile文件,再将Flutter镜像+Flutter环境变量添加到bash_profile文件中)
2.1 配置Flutter镜像
2.1.1 进入当前用户的home目录:cd ~/
2.1.2 创建.bash_profile文件:touch .bash_profile
2.1.3 打开.bash_profile并编辑:open .bash_profile ( 或者用:open $HOME/.bash_profile)
(以下三个镜像三选一,我一开始用的清华的,报错:curl: (60) SSL certificate problem: certificate has expired,后面换成官方提供的就👌了)
# 官方提供的国内镜像
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
# 上海交通大学提供的国内镜像
export PUB_HOSTED_URL=https://dart-pub.mirrors.sjtug.sjtu.edu.cn/
export FLUTTER_STORAGE_BASE_URL=https://mirrors.sjtug.sjtu.edu.cn/
#清华提供的国内镜像
export FLUTTER_STORAGE_BASE_URL=https://mirrors.tuna.tsinghua.edu.cn/flutter
export PUB_HOSTED_URL=https://mirrors.tuna.tsinghua.edu.cn/dart-pub
2.2 配置Flutter环境变量,将环境变量添加至末尾。
#Flutter环境变量
export PATH="$PATH:/Users/liuguimei/Documents/flutterSDK/bin"
//我把下载的flutter文件放在了电脑的文稿里,而且用flutterSDK代替了下载的flutter这个外层文件名
2.3 如终端安装了zsh插件,则按上面步骤添加环境变量至 ~/.zshrc
3、 刷新环境变量
source ~/.bash_profile
source ~/.zshrc(如安装zsh插件)
4、运行 flutter doctor
5、开发工具
5.1. Xcode + Android Studio
5.2. Visual Studio Code

遇到的问题
问题一:cmdline-tools component is missing
解决办法:
1、打开Android Studio 偏好设置

2、操作如图示,就解决了。
问题二:Android toolchain - develop for Android devices (Android SDK version 31.0.0)
! Some Android licenses not accepted. To resolve this, run: flutter doctor
--android-licenses
解决办法:
命令行跑 flutter doctor --android-licenses,
Review licenses that have not been accepted (y/N)? y 一路输入y,就解决了。
解决问题后跑flutter doctor,就可以看到安装的flutter的最新情况。
