Description

Thank you for your mapper. It is very useful for apps.

I am using kotlin data classes with val params:
data class Person (
var id: Int?=null
val name: String
val documentId: String
...
)
I can't use empty constructor due to notNull notation.
I could be wrong, at present time mapper demands empty constructors.

Is it possible to add mapper that uses args constructor?

Thank you,
Irina
