Is there a way to know when a flow is entered or exited?

[logynapp]

 DestinationsNavHost(
                navGraph = NavGraphs.root,
                engine = engine,
                startRoute = NavGraphs.root.startRoute,
                dependenciesContainerBuilder = {

                    dependency(NavGraphs.root) {
                        mainViewModel
                    }


                    dependency(NavGraphs.basicInfo) {
                        org.koin.compose.getKoin().getOrCreateScope(
                            scopeId = "basicFlow",
                            qualifier = named("basicFlow")
                        ).get<BasicInfoViewModel>()
                    }

                    dependency(NavGraphs.iceNavGraph) {
                        org.koin.compose.getKoin().getOrCreateScope(
                            scopeId = "iceFlow",
                            qualifier = named("iceFlow")
                        ).get<IceInfoViewModel>()
                    }


                }
            )

what I want to achieve is to destroy the scope or to be more precise to clear the graph dependencies after exiting like to clear koin scope after navigating away from the graph.

I assume you mean a nested graph?

This is a question for the official library, since we haven't really changed this functionality.
I believe (I did not test it) you can add a lifecycle observer to iceNavGraph like this:

navController.getBackStackEntry(NavGraphs.iceNavGraph.route).lifecycle.addObserver(
    object : DefaultLifecycleObserver {
        override fun onDestroy(owner: LifecycleOwner) {
            // should be called when iceNavGraph leaves the backstack I believe
        }
    }
)

Let me know if this works for you, I'll go ahead and close it.
