backPresses

the LifecycleOwner which controls when the callback should be invoked.

Note: Created flow keeps a strong reference to the OnBackPressedDispatcher instance until the coroutine that launched the flow collector is cancelled.

Example of usage:

onBackPressedDispatcher.backPresses(lifecycleOwner)
    .onEach {
         // handle back pressed
    }
    .launchIn(uiScope)
