How to convert ArrayList<String> to a\array<out String> in kotlin

Question

my Data.builder() method putStringArray() takes parameter as key : String and value : Array

how do I convert my ArrayList into Array?

fun createInputData(dataItems : ArrayList<String>) : Data
    {
       
        return Data.Builder()
                .putStringArray("dataItems",dataItems)
                .build()
    }

the above code doesn't work.

Answer 1

dataItems.toTypedArray() should do the trick
