Cannot build IOS app due to CocoaPods could not find compatible versions for pod "Firebase/CoreOnly"

Question

When attempting to build the Flutter app on an "Apple MAC M1," I encountered an error. I attempted to resolve it by executing the following command:

#!/usr/bin/env bash

rm -rf Podfile.lock && flutter build ios && arch -x86_64 pod install

The error was related to CocoaPods not finding compatible versions for the pod "Firebase/CoreOnly." Specifically, the versions identified were:

In the Podfile.lock snapshot:

• Firebase/CoreOnly (= 10.20.0)

In the Podfile:

• firebase_core (from .symlinks/plugins/firebase_core/ios) was resolved to 3.1.0, which requires Firebase/CoreOnly (= 10.27.0)

Detailed error

      In Podfile:

    You have either:
     * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
     * changed the constraints of dependency `Firebase/CoreOnly` inside your development pod `firebase_core`.
       You should run `pod update Firebase/CoreOnly` to apply changes you've made.

To update the CocoaPods specs, run:
  pod repo update

Error running pod install

Due to the lack of a macOS machine, I used "Codemagic" for building and publishing the app.

I tried resolving this by browsing several articles on Stack Overflow, but they were somewhat outdated and didn't help me. That's why I'm asking this.

I attempted to update all Firebase packages, but the issue persisted. I also experimented with various Flutter versions like "3.19.0," "3.22.0," "3.22.2," and "3.23.0-0.1-pre," along with different CocoaPods versions like "1.15.2" and "1.15.0," but unfortunately, no solution was found.
