Additional context
I'm trying to upgrade the flutter_background_geolocation library to 5.0.5 and also flutter to 3.29.3 but I'm encountering the error. Some things to note:

• I've cloned the flutter_background_geolocation_firebase repo and removed all the v2 references to get it to build.
• We are already using an updated flutter_background_geolocation license, we've moved to v5 now.
• I've tried removing the references to the flutter_background_geolocation_firebase in code and everything works ok minus the saving to firebase.
