@tlserver Please update!! 🙏🏼

flutter pub add flutter_map_location_marker
The current Dart SDK version is 3.12.2.

Because flutter_map_location_marker >=1.0.0-nullsafety.0 <1.0.0 depends on latlong2 ^0.8.0 and flutter_map_location_marker
  <1.0.0-nullsafety.0 doesn't support null safety, flutter_map_location_marker <=1.0.0-nullsafety.0 requires latlong2 ^0.8.0.
And because flutter_map_location_marker >=1.0.0 <7.0.0 depends on latlong2 ^0.8.1, flutter_map_location_marker <7.0.0 requires
  latlong2 ^0.8.0.
And because flutter_map_location_marker >=7.0.0 <9.0.0 depends on latlong2 ^0.9.0 and flutter_map_location_marker >=9.0.0 depends
  on latlong2 ^0.9.1, every version of flutter_map_location_marker requires latlong2 ^0.8.0 or >=0.9.0 <0.10.0.
So, because my_app depends on both latlong2 ^0.10.1 and flutter_map_location_marker any, version solving failed.

The lower bound of "sdk: '>=2.3.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.
