Flutter AdMob works on Android but not on iOS - flutter

Question

I have a Flutter project that uses AdMob. This works fine in Android and I'm able to view the test ads. But when I try to build for iOS, the build fails. I've googled for this and tried out various suggestions I found online but nothing helped. Hope someone can help with this issue.
snippets from my pub spec.yaml file
environment:
sdk: ">=2.7.0 <3.0.0"
firebase_core: ^0.7.0
firebase_admob: ^0.11.0+1
In ios/Flutter/AppFrameworkInfo.plist MinimumOSVersion is set to 10.1. And finally here are my build errors
Xcode's output:

Add to Podfile:
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
# TODO: remove this once this issue is resolved:
# https://github.com/FirebaseExtended/flutterfire/issues/4931
pod 'Google-Mobile-Ads-SDK', '~> 7.69.0' # this line
end
