you need a mutable map to be able to insert new pairs https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/mutable-map-of.html

your map is mutable, but then you narrow the type down to immutable

either do

val parameters = HashMap<String, List<String>>()

val parameters: MutableMap<String, List<String>> = HashMap()

val parameters = mutableMapOf<String, List<String>>()

I assumed he cared about the implementing type, but if you don't care about it, that's the best one to use

Thanks guys.

I managed to implement it.

I though if I don't defined anything.

I would be MutableList by default.

only if it comes from Java

Let's not get into the ways we could do this. This is Kotlin, we'd be here all year :p
