问题描述
最新更新了Flutter SDK到最新版本，然后使用doctor命令检查环境发现以下警告.
wangyangyangdeMacBook-Pro:fusion_pro wangyang$ flutter doctor -v [!] Flutter (Channel stable, 3.7.9, on macOS 12.6.5 21G531 darwin-x64, locale zh-Hans-CN) • Flutter version 3.7.9 on channel stable at /Users/wangyang/Developer/develop_env/flutter_3.7.9 !

解决方案
Warning: dart on your path resolves to /usr/local/Cellar/dart/2.13.3/libexec/bin/dart, which is not inside your current Flutter SDK checkout at
/Users/wangyang/Developer/develop_env/flutter_3.7.9. Consider adding /Users/wangyang/Developer/develop_env/flutter_3.7.9/bin to the front of your
path.
看警告提示是检查到了单独的Dart SDK，不是在Flutter SDK之中，建议我们将Flutter中的Dart路径添加到环境变量中。
说白了就是系统中存在了2个Dart SDK，我们只需要将单独的Dart SDk删除就好。
根据路径Cellar，我们判断出这是以前使用homebrew安装的Dart。
我们使用brew list查看是否安装过.
发现确实安装过, 我们使用brew remove dart来卸载Dart.
wangyangyangdeMacBook-Pro:~ wangyang$ brew remove dart Uninstalling /usr/local/Cellar/dart/2.13.3... (508 files, 477MB)
可以看到卸载的路径正好对应了警告中的路径，说明确实是这个Dart引发的警告。
再次运行flutter doctor -v, 警告消失，搞定!
