onReceiveOrNull

defined on

ReceiveChannel

interface is now deprecated, and

onReceiveOrNull

extension function defined on

ReceiveChannel

is now

ExperimentalCoroutinesApi

. I'm trying to use extension version of onReceiveOrNull but I can't. Is there anything wrong?

As real non extension functions are preferred over extension functions you can't call it with that name. You could do:

import kotlinx.coroutines.channels.onRecieveOrNull as onRecieveOrNullExtension

And use

onRecieveOrNullExtension

instead of

onRecieveOrNull

Oh, it's Kotlin's grammatical rule,,,, Thanks! It works fine for me!
