Query firestore documents based on geographic radius
from geoFirePoint center
field
specifies the name of the key in the document
returns merged stream as broadcast stream.
Returns original stream from the underlying rxdart implementation, which could be safely cancelled without memory leaks. It's single stream subscription, so only single listener could be created at a time.
This works the best if you have central point of listening for locations, not per widget.
