Is there a better way to do function calls similar to this?

someFunction(  // takes varargs
    *arrayOf(if (condition) "someValue" else null).filterNotNull().toTypedArray(),
)

[wbertan]

Maybe with listOfNotNull?

[ephemient]

someFunction(
    *if (condition) arrayOf("someValue") else emptyArray()
)

I like ephemient's solution but some people may find the following simpler-looking and more readable:

if (condition)
    someFunction("someValue")
else
    someFunction()

Or extract it out:

fun anotherFunction(condition: Boolean) = 
  if (condition)
    arrayOf("someValue")
  else
    emptyArray()

At least then the “condition” is now testable alone, as it would have been buried in the call of another function and therefore obfuscated.

someFunction(*anotherFunction(condition))
