Is there a way to pass function with optional argument like

fun fetchData(page=0) {...}

to a function that expects a function with no argument like?

fun runRequest(block: ()->Unit)

[kralli]

You mean like runRequest(::fetchData)?

[Saiedmomen]

yep

[Saiedmomen]

I thought there might be sth like @JvmOverloads that I've missed

[Big Chungus]

fun runRequest(block: (()->Unit)? = null)

Function type behaves just like any other type and thus can be nullable. You can also pass in the default implementation such as

fun runRequest(block: (()->Unit) = {})
