Because every version of geo_firestore depends on cloud_firestore ^0.12.2 and your app depends on cloud_firestore ^0.13.4+2, geo_firestore is forbidden.
So, because nothing_new depends on geo_firestore ^0.0.1, version solving failed.
pub upgrade failed (1; So, because nothing_new depends on geo_firestore ^0.0.1, version solving failed.)
Bit late, but in case anyone else is wondering, I created a fork of this project and am actively maintaining it since I'm using it in a production app. I use a different data structure, but if you haven't compiled your db yet, this shouldn't be a problem.
See the results of
flutter pub upgrade
