Warning! This package referenced a Flutter repository via the .packages file that is no longer available. The repository from which the 'flutter' tool is currently executing will be used instead.
  running Flutter tool: /Users/gzc/Documents/developer/flutter
  previous reference  : /Users/doc/Flutter/flutter
This can happen if you deleted or moved your copy of the Flutter repository, or if it was on a volume that is no longer mounted or has been mounted at a different location. Please check your system path to verify that you are running the expected version (run 'flutter --version' to see which flutter is on your path).

解决方案

RunCommand find "${derived_dir}/engine/Flutter.framework" -type f -exec chmod a-w "{}" \;
=>
RunCommand find "${derived_dir}/engine/Flutter.framework" -type f -iname '.h' -exec chmod a-w "{}" \;

解决方案：
删除pods、.lock文件 并清除缓存 重新pod install一下

在flutter项目中添加依赖可能出现如下错误：
A dependency may only have one source
位置没对齐的原因造成的

改为下面的样式

dependencies:
  flutter:
    sdk: flutter
  dio: ^3.0.9
