class SnackbarState {
    var show by mutableStateOf(false)

fun TransientSnackbar(
    modifier: Modifier = Modifier,
    snackbarState: SnackbarState,
    text: String,
    actionLabel: String,
    onAction: () -> Unit,
    shape: Shape = MaterialTheme.shapes.small,
    autoDismiss: Boolean = true,

            text = { Text(text = text) },
            shape = shape,
            action = {
                ClickableText(
                    text = AnnotatedString(text = actionLabel),
                    modifier = Modifier.padding(16.dp),
                    style = TextStyle(
                        fontWeight = FontWeight.Bold,
                        color = MaterialTheme.colors.secondary
                    ),
                    onClick = {
                        onAction()
                        snackbarState.show = false
                    }
                )
            }
        )
    }

     if (autoDismiss && snackbarState.show) {
        launchInComposition {
            delay(timeout)
            snackbarState.show = false
            onDismiss(snackbarState)
        }
    }
}

Looks cool, but how to add dynamically?🤔
