环境配置流程
在配置flutter环境之前，先配置好xcode环境 和 Android Studio环境，这两个配置好之后flutter的环境配置会顺利很多。
下载flutter SDK
//将仓库克隆到合适的目录下
git clone https://github.com/flutter/flutter.git
切分支
切换分支到 stable,这是最新的稳定版本。
如果想使用特定版本，请将 stable 分支 reset 到指定的tag处即可。
注意：不要直接选中tag，然后checkout，这样后面在flutter doctor时会有警告提示，未在官方channel上
设置环境变量
#Dart配置
export PATH=$PATH:/Users/lixiaoyi/FlutterSDK/flutter_flutter/bin/cache/dart-sdk/bin
# Flutter 国内镜像
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
# Flutter 拉取下来的flutter_flutter/bin目录
export FLUTTER=/Users/lixiaoyi/FlutterSDK/flutter/bin
#export FLUTTER=/Users/lixiaoyi/FlutterSDK/flutter_flutter/bin
export PATH=$FLUTTER:$PATH
# Flutter 相关Url配置
export FLUTTER_GIT_URL=https://github.com/flutter/flutter.git
#export FLUTTER_GIT_URL=https://gitee.com/openharmony-sig/flutter_flutter.git
检查是否配置成功
// 查看flutter 版本
flutter --version
// 环境诊断,如果有问题请根据提示进行修复
flutter doctor
flutter doctor -v
遇到的问题
Xcode配置引起的问题
执行flutter doctor时，报 xcrun:error 是因为xcode得命令行工具找不到。指定下位置即可。
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/
Android Studio配置引起的问题
执行flutter doctor时，报红提示找不到 java runtime ,并且 Android Studio 报错 Unable to find bundled Java version.
╰─ flutter doctor

搜索资料后发现没有配置 JAVA_HOME 环境变量，配置了 JAVA_HOME 环境变量后执行 flutter doctor
注意：.zshrc文件内配置了下面两项时 echo $JAVA_HOME 无法输出内容
export PATH="$HOME/.jenv/bin:$PATH"
// 注释掉该行，echo $JAVA_HOME 才生效
# eval "$(jenv init -)"
但注释之后运行flutter doctor，只是少了 找不到 java runtime 的错误提示，但 Android Studio 仍然报错

将flutter sdk 切换到最新版本flutter doctor就不会报错，所以怀疑是不是 最新下载的Android Studio 和 老版本的flutter sdk不兼容。
后来搜索资料，发现一篇文章下面的评论内提到一个方法尝试了下解决了。
在应用程序内找到 Android Studio 右键打开包内容
在content目录下 创建一个jre文件夹
将jbr目录下的所有内容拷贝一份到jre文件夹内
重启终端执行 flutter doctor 然后就成功了。
后续研究研究这两个文件夹的作用。
行者常至，为者常成！
