Because stacked_themes >=0.2.4 depends on rxdart ^0.26.0 and geoflutterfire 3.0.0-nullsafety.4 depends on rxdart ^0.27.0, stacked_themes >=0.2.4 is incompatible with geoflutterfire 3.0.0-nullsafety.4.
So, because app depends on both geoflutterfire 3.0.0-nullsafety.4 and stacked_themes 0.3.1, version solving failed.
