pod command is not recognized when running flutter project

I have tried every suggestion and solution in stack overflow and GitHub and yet I am not able to run pod install and I get pod : command not found , also my pod file is empty.

 Warning: CocoaPods not installed. Skipping pod install.
  CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds
  to your plugin usage on the Dart side.
  Without CocoaPods, plugins will not work on iOS or macOS.
  For more info, see https://flutter.dev/platform-plugins
To install:
  sudo gem install cocoapods
