It seems that the issue is with pod 'FBSDKCoreKit', '18.0.2'

I override to use pod 'FBSDKCoreKit', '18.0.0' and it build successfully.

target 'Runner' do
  pod 'GoogleUtilities'
  use_frameworks!
  use_modular_headers!

  # This is just a temporary solution to fix the iOS build issue https://github.com/oddbit/flutter_facebook_app_events/issues/451
  pod 'FBSDKCoreKit', '18.0.0'

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

I realize after applying your temp fix, it's still failed building.

@hackerG7
After adding FBSDKCoreKit do-

• dart pub cache clean
• flutter pub get
• @cd ios && rm -rf Pods/ Podfile.lock
  @cd ios && pod repo update && pod install && pod update
  It will build but as @deepak-agendaboa mentioned its a temp fix !
