I’m having some difficulties to understand how one can get an instance of a FlowCollector or anything build through the builder helpers function like flow { }, callbackFlow { }, etc... .
What I want is to be able to do something like that from my fragment (or activity) but in a “correct” way

private lateinit var collector: FlowCollector<MainFragmentEvent>

private val events = flow<MainFragmentEvent> {
    collector = this
}

override onResume() {
    lifecycleScope.launch {
        collector.emit(MainFragmentEvent.ResumeEvent(requireContext()))
    }
}

Can I do that only by using Channel, SendChannel, etc... and then convert it some how to a Flow ?

This would be a great use case for the proposed EventFlow, but since that doesn't exist yet you can use BroadcastChannel, which has an asFlow() extension method.
