CocoaPods could not find compatible versions for pod "FirebaseCore" : error on running pod install for flutter iOS build

I am getting this error below on running "pod install" with the latest firebase_core sdk, on flutter for iOS. I cleared the Pod, symlinks folders and deleted the Podfile.lock file, and ran pod install, but the result is the same as below. What is the issue here?

    Flutter mlkit plugin does not support Firebase version 10, therefor you need to downgrade.

    Compatible dependencies:

    google_mlkit_text_recognition: ^0.5.0
firebase_core: ^1.24.0
firebase_analytics: ^9.1.5
cloud_firestore: ^3.5.1
firebase_crashlytics: ^2.9.0
firebase_auth: ^3.11.2

dependency_overrides:
    firebase_core_platform_interface: 4.5.1

    Add this in top of Podfile

    $FirebaseSDKVersion = '9.6.0'
