CocoaPods could not find compatible versions for pod "FirebaseCore":

[sswedan]

I have a flutter app that was working correctly without any issue. yesterday I have to update to the latest Flutter version (3.24.5).

I started to get the following error on

_fcmToken = await _messaging.getToken();

"flutter error while checking the internet connection firebase_messaging/unknown an unknown error occurred"

I had to upgrade to the latest firebase packages as shown:

  firebase_core: ^3.8.0
  firebase_analytics: ^11.3.5
  firebase_messaging: ^15.1.5

ios version in Podfile:
platform :ios, '13.0'

now when I run "pod install" I get the below error:

I tried a lot of things and nothing helped. Can anyone please help me with this issue?

turns out mobile_scanner needed to be updated to the latest version 6.0.2 and the platform :ios, '15.5'
