what's the best way to emit the results of one flow into another? For example i am using a bluetooth library that has states for Connected and Disconnected as a StateFlow . I am trying to add more states such as Connecting or LookingForSavedDevice at a higher level in my program so I would like to use a StateFlow which both takes in emissions from the library functions as well as allow me to mutate the StateFlow myself.

So I think I'm looking for a way to collect into another flow:
bluetoothLibrary.stateFlow.collect(myOtherStateFlow)

I'm aware I can just emit into the new flow in a collect { } block or onEach { } but I'm not sure what is canonical

[ephemient]

myOtherStateFlow.emitAll(bluetoothLibrary.stateFlow)

is equivalent to

bluetoothLibrary.stateFlow.collect { myOtherStateFlow.emit(it) }

but is that really what you want? in most cases I'd consider

val myFlow = merge(
    bluetoothLibrary.stateFlow,
    myOtherStateFlow,
)

to be better than having multiple mutators of a single MutableStateFlow

I agree that might be cleaner to just use a merge . I'll have to check if that still returns a StateFlow or just a Flow at that point but otherwise that's a great idea. Thank you
