Cocoapods Compatibility Error - Error Running Pod Install

Many similar questions have been asked here and on Github but none of the solutions worked for me. I've been scratching my head off for this error, if you have any leads, do help.

When running my app, with firebase authentication, this is what I get

    [!] CocoaPods could not find compatible versions for pod "cloud_firestore":
      In Podfile:
        cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)
    Specs satisfying the `cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)` dependency were found, but they required a higher minimum deployment target.

Error running pod install
Error launching application on iPhone 12.

I tried removing the Podfile, uncommenting the "version: '9.0'" in the Podfile, flutter clean, and everything but nothing worked. What am i exactly doing wrong?

as mentioned in the ios documentation of FlutterFire (which should be more highlighted), FlutterFire supports an iOS deployment target of 10 or higher, in line with the requirements of the underlying firebase-ios-sdk.

the solution, is to follow what the instructions here, and set the deployment target to 10.

do not forget to run a flutter clean after the changes.
