How do I dynamically instantiate

Person

having a map of constructor arguments?

Copy code

data class Person(val id: Int, val name: String, val age: Int?)

Copy code

val args = mapOf("id" to 1, "name" to "Alice")
val newPerson = ???

Find the constructor you want inside

KClass.constructors

then use

callBy

on that.

Convert to

KClass

using

jClassInstance.kotlin
