Running command flutter doctor -v drops this error CocoaPods installed but not working. You appear to have CocoaPods installed but it is not working.

✗ CocoaPods installed but not working.
You appear to have CocoaPods installed but it is not working.
This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to
invoke it.
This can usually be fixed by re-installing CocoaPods.
To re-install see https://guides.cocoapods.org/using/getting-started.html#installation for instructions.
