Thanks,
What is the precision of Geofire query for distance?

GeoFire encodes the latitude and longitude into a GeoHash value. The accuracy of a GeoHash value depends on the input data, the number of characters used to encode the location and the distance of the location from the equator.
It defaults to using 10 characters for the encoding, as you can see in the source code. This is (as far as I can tell) roughly accurate up to a meter.
But the library can handle encoding up to 22 characters in length if you invoke the constructor that takes a precision parameter.
