Hi! I have an inline function that is binding the state to a lifecycle owner.

inline fun <A> Flow<A>.bindState(
    lifecycleOwner: LifecycleOwner,
    crossinline bind: suspend (A) -> Unit,
) =
    lifecycleOwner.lifecycleScope.launchWhenStarted {
        collect(bind)
    }

Recently I've updated the coroutines library to 1.6.4 (from 1.5.2) and looks like Flow.collect(crossinline action: suspend (value: T) -> Unit) doesn't work with the newer version of coroutines dependencies. Flow.collect() now takes a FlowCollector functional interface argument instead of a suspend (T) -> Unit. Any suggestions of how I can still keep this as an inline function?

This is what I was thinking of, but not sure if that's the best approach:

inline fun <A> Flow<A>.bindState(
    lifecycleOwner: LifecycleOwner,
    crossinline action: suspend (A) -> Unit,
) =
    lifecycleOwner.lifecycleScope.launchWhenStarted {
        collect(object : FlowCollector<A> {
            override suspend fun emit(value: A) = action(value)
        })
    }

This is interesting, I hadn’t spotted this had changed! I have often noticed weirdness when trying to import the right collect function, though 😞.

Since it’s a fun interface, FlowCollector(action) should work instead of the anonymous object
