google's services "sabotage" local build

when I try to build using flutter build ios on my local computer, I am unable to install pod:
   W/"65d-mjv8UNq4TdpVq3/Rw685EgeY6lc"

    [!] CocoaPods could not find compatible versions for pod "Firebase/Messaging":

      In Podfile:

        Firebase/Messaging (= 11.00.0)

        firebase_messaging (from .symlinks/plugins/firebase_messaging/ios) was resolved to 15.1.1, which depends on

          Firebase/Messaging (= 11.0.0)

    None of your spec sources contain a spec satisfying the dependencies: Firebase/Messaging (= 11.00.0), Firebase/Messaging (= 11.0.0).

    You have either:

     * out-of-date source repos which you can update with pod repo update or with pod install --repo-update.

     * mistyped the name or version.

     * not added the source repo that hosts the Podspec to your Podfile.

Error: CocoaPods's specs repository is too out-of-date to satisfy dependencies.

To update the CocoaPods specs, run:

  pod repo update
