# compose

Could someone explain please, why there is no exit animation for Snackbar?
I have the following code:

data class State(val snackMessage: String? = null) // hoisted in ViewModel

//show snackbars inside root Composable
LaunchedEffect(state.snackMessage) {
  if (state.snackMessage != null) {
    snackbarHostState.showSnackbar(state.snackMessage)
    viewModel.shackbarShown() // this make a copy of the state with snackMessage = null
  }
}

So then I emit a new instance of state with snackMessage = null , I expect that I see animation but instead it’s just gone.
I’ve made some experiment and removed the line viewModel.shackbarShown() and then the exit animation was played…
