[Flutter] Flutter - Firebase Core - Error Searching for inspections failed: undefined method...

I am trying to configure my Flutter app with Firebase and am having no luck just getting the app to run after adding firebase_core: ^3.1.0

Here's what has happened thus far.

1. 
   flutter pub add firebase_core
   
   
2. 
   tried launching the app and received the following error:
   
   Error: The plugin "firebase_core" requires a higher minimum iOS deployment version than your application is targeting. To build, increase your application's deployment target to at least 13.0 as described at https://docs.flutter.dev/deployment/ios
   
   
3. 
   Modified the ios/PodFile by uncommenting the following line and change '12.0' to '13.0'
   
   platform :ios, '13.0'
   
   
4. 
   Then I got the following error:
   
   Error output from CocoaPods: ↳ Searching for inspections failed: undefined method `map' for nil:NilClass
   
   Error running pod install Error launching application on iPhone 15 Pro Max.
   

Any assistance is appreciated.
