firebase_core Unable to build with firebase_core: 0.4.4+2

[TylerSustare]

Describe the bug

This bug is representing the comment I made here on the closed issue. flutter/flutter#35670 (comment)
Even trying @sensuikan1973's suggestion in the linked issue didn't work.

• flutter clean
• Clean Build Folder from Xcode
• delete Podfile.lock

But, this didn't work.

So, I deintegrate pod.

cd ios
pod deintegrate
pod install

To Reproduce

Steps to reproduce the behavior:
Attempting to build and run an iOS app with firebase_core: ^0.4.4+2 lead to

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...
Xcode build done.                                            5.6s

Could not build the application for the simulator.

Expected behavior

Starting the app using firebase_core: ^0.4.4+2 the same way it does when I use firebase_core: 0.4.3+3

Additional context

the rest of my firebase packages in pubspec.yaml

dependencies:
  flutter:
    sdk: flutter
  provider: ^4.0.4

  firebase_core: 0.4.3+3
  firebase_auth: ^0.15.4
  cloud_firestore: ^0.13.2+1
  firebase_analytics: ^5.0.11

Same problem :(

I downgraded the version as mentioned above, and it caused conflict with firestore cloud storage version. Than i downgraded that too at cloud_firestore: 0.13.2 and i was able to install the app

Having the same problem.

For anyone like me who kept the ^ in the version, remove it otherwise it will keep using newer versions.

I can confirm that this fixed it for me. Downgrading to cloud_firestore: 0.13.2 and firebase_core: 0.4.3+3 works.

@everyone - can anyone please add a comprehensive list of package versions that would work with the reduced versions of firebase_core please? I have run through the releases list, and used the versions listed there that are prior to the latest firebase_core release... however this does not appear to do the trick. I feel like there are a few un tagged versions that are just not in the list. Thanks in advance for putting this together!
