[FirebaseMessaging][][!] CocoaPods could not find compatible versions for pod "FirebaseMessaging":

Pre-downloading: `FirebaseFirestore` from `https://github.com/invertase/firestore-ios-sdk-frameworks.git`, tag `7.11.0`


firebase_core: Using Firebase SDK version '7.3.0' defined in 'firebase_core'
firebase_messaging: Using Firebase SDK version '7.3.0' defined in 'firebase_core'
[!] CocoaPods could not find compatible versions for pod "FirebaseMessaging":
  In snapshot (Podfile.lock):
    FirebaseMessaging (= 4.7.1, ~> 4.7.0)

  In Podfile:
    firebase_messaging (from `.symlinks/plugins/firebase_messaging/ios`) was resolved to 9.1.2, which depends on
      Firebase/Messaging (= 7.3.0) was resolved to 7.3.0, which depends on
        FirebaseMessaging (~> 7.3.0)


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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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 `FirebaseMessaging` inside your development pod `firebase_messaging`.
   You should run `pod update FirebaseMessaging` to apply changes you've made.

[!] Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

ios podfile:

Changing to 7.3.0 is the same problem

  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '7.11.0'

Flutter 2.0.4
pubspec.yaml:

  firebase_core: ^1.0.4
  firebase_messaging: ^9.1.2
