Snackbar

Must call snackBar in a coroutineScope

val scope = rememberCoroutineScope()
val snackbarHostState = remember { SnackbarHostState() }
Scaffold(
    snackbarHost = {
        SnackbarHost(hostState = snackbarHostState)
    },
    floatingActionButton = {
        ExtendedFloatingActionButton(
            text = { Text("Show snackbar") },
            icon = { Icon(Icons.Filled.Image, contentDescription = "") },
            onClick = {
                scope.launch {
                    snackbarHostState.showSnackbar("Snackbar")
                }
            }
        )
    }
) { contentPadding ->
    // Screen content
}

Add action or duration

val result = snackbarHostState
    .showSnackbar(
        message = "Snackbar",
        actionLabel = "Action",
        // Defaults to SnackbarDuration.Short
        duration = SnackbarDuration.Indefinite
    )
when (result) {
    SnackbarResult.ActionPerformed -> {
        /* Handle snackbar action performed */
    }
    SnackbarResult.Dismissed -> {
        /* Handle snackbar dismissed */
    }
}
