Flutter Cannot complie project when using Firebase In App Messaging plugin

I successfully implemented the plugin on android but when I try to start the app on ios I'm getting an error message. When I disable the plugin and reinstall the app on ios, everything works just fine. Here is my console log:

Launching lib/main.dart on iPhone 5s in debug mode...
Running pod install...
Warning: Podfile is out of date
  This can cause a mismatched version of Flutter to be embedded in your app, which may result in App Store submission rejection or crashes.
  If you have local Podfile edits you would like to keep, see https://github.com/flutter/flutter/issues/24641 for instructions.
To regenerate the Podfile, run:
  rm ios/Podfile
