Is there a way to pass function with optional argument like
Copy code
fun fetchData(page=0) {...}
to a function that expects a function with no argument like?
Copy code
fun runRequest(block: ()->Unit)

You mean like
runRequest(::fetchData)
?

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