[FIXED] Android Kotlin function with multiple optional parameters, call function only with parameters at specific place

Issue

So I have this function that has 8 optional parameters (yes I know it's bad practice to have that much, this is legacy code :D).

It goes something like this:

private fun function(
    rightImage: Int = 0,
    background: Int = R.drawable.account_item_bg,
    leftImage: Int = 0,
    translation: String? = null,
    name: String? = null,
    age: String? = null,
    length: String? = null,
    duration: String? = null)

Now in my code, I want to call this function and give it only the last parameter (duration). I don't care for other ones.

But at the moment to call this, I Would do it like this:

function(0, R.drawable.account_item_bg, 0, null, null, null, null, 1800)

I was just thinking in the moment of writing this code that it would be cool to have option to send only parameters at the particular place (f.e parameter 6, or last parameter), and not repeat all the optional ones.

Is there maybe option like this, does anyone know? Thanks

Solution

This is what you're looking for.

Example code:

function(duration = "1800")
