The artifact failure details are included below:

File name: app/radio_qth_map/pubspec.lock

Command failed: flutter pub upgrade firebase_core
Because firebase_auth >=4.17.4 <4.17.6 depends on firebase_core ^2.25.4 and firebase_auth >=4.17.7 <4.17.8 depends on firebase_core ^2.26.0, firebase_auth >=4.17.4 <4.17.6-∞ or >=4.17.7 <4.17.8-∞ requires firebase_core ^2.25.4.
And because firebase_auth >=4.17.8 <4.17.9 depends on firebase_core ^2.27.0, firebase_auth >=4.17.4 <4.17.6-∞ or >=4.17.7 <4.17.9-∞ requires firebase_core ^2.25.4.
And because firebase_auth >=4.17.9 <4.18.0 depends on firebase_core ^2.27.1 and firebase_auth >=4.18.0 <4.19.0 depends on firebase_core ^2.27.2, firebase_auth >=4.17.4 <4.17.6-∞ or >=4.17.7 <4.19.0-∞ requires firebase_core ^2.25.4.
And because firebase_auth >=4.19.0 <4.19.1 depends on firebase_core ^2.28.0 and firebase_auth >=4.19.1 <4.19.2 depends on firebase_core ^2.29.0, firebase_auth >=4.17.4 <4.17.6-∞ or >=4.17.7 <4.19.2-∞ requires firebase_core ^2.25.4.
And because firebase_auth >=4.19.2 <4.19.3 depends on firebase_core ^2.30.0 and firebase_auth >=4.19.3 <4.19.5 depends on firebase_core ^2.30.1, firebase_auth >=4.17.4 <4.17.6-∞ or >=4.17.7 <4.19.5-∞ requires firebase_core ^2.25.4.
And because firebase_auth >=4.19.5 <4.19.6 depends on firebase_core ^2.31.0 and firebase_auth >=4.19.6 <4.20.0 depends on firebase_core ^2.31.1, firebase_auth >=4.17.4 <4.17.6-∞ or >=4.17.7 <4.20.0-∞ requires firebase_core ^2.25.4.
And because firebase_auth ^4.20.0 depends on firebase_core ^2.32.0 and firebase_auth >=4.17.6 <4.17.7 depends on firebase_core ^2.25.5, firebase_auth ^4.17.4 requires firebase_core ^2.25.4.
So, because radio_qth_map depends on both firebase_core ^3.0.0 and firebase_auth ^4.17.4, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on firebase_core: flutter pub add firebase_core:^2.27.0
