Hey !

It would be very nice to have a way to link the properties to their json keys. It would reduce the margin of error. For exemple, in my case, it would be for Firebase filters.

from : Filter('datetime_start', isGreaterThan: ...)
to : Filter(MyModel.jsonKeys.dateTimeStart, isGreaterThan: ...)

I know there already is the parameter 'create_field_map' which allows for Filter(MyModel.fieldMap['dateTimeStart'], isGreaterThan: ...) but it's safer to use properties instead of strings.
