Thanks for the report. I am seeing same behavior as reported:

Exception: Error running pod install
dhs@Dhss-MacBook-Pro firebase_core_example % 

As the error message says dependency were found, but they required a higher minimum deployment target., in current firebase_core exmple, the macos/podfile shows platform :osx, '10.12'. If we manually change it to 10.13, it works and compiles properly.

According to this PR : #9708, the podspec was updated to iOS and macOS to show updated minimum deployment target, ie, 10.13, but for some reason, in firebase_core example, the macos/podfile still shows as 10.12.

I checked for other plugins, for instance, firebase_auth, for which the macos/podfile is showing correct updated target, https://github.com/firebase/flutterfire/blob/master/packages/firebase_auth/firebase_auth/example/macos/Podfile

Another example, firebase_analytics, also shows platform :osx, '10.12' and then gives same error as reported, although it does show a meaningful log as below:

[!] Failed to load 'firebase_analytics' podspec: 
    [!] Invalid `firebase_analytics.podspec` file: [!] The FlutterFire plugin firebase_analytics for macOS requires a macOS deployment target of 10.13 or later..

Which probably is not shown for firebase_core.

Keeping this issue open for further insights from the team.

As @darshankawar said, you just need to update your macos/Podfile to a higher deployment target: 10.13. We are tracking updating example apps in another issue .
