When I make a function that takes a lambda, I write it like this:

Copy code

fun findProject(id: String, callback: (Project?) -> Unit)

That works great for Kotlin. When interopping with Java, that function has to return a value, so I have to add a

return null

to the end of it, which is a bit awkward. Is there a way around that?
