Snackbar

fun UiTreeBuilder.Snackbar(visible: Boolean, message: String, actionLabel: String? = null, duration: SnackbarDuration = SnackbarDuration.Short, queuePolicy: TransientFeedbackQueuePolicy = TransientFeedbackQueuePolicy.Enqueue, requestKey: String = "snackbar", onAction: () -> Unit? = null, onDismiss: (TransientFeedbackDismissReason) -> Unit? = null)(source)

Submits a keyed snackbar request to the active overlay presenter.

No request is submitted when visible is false. Duration and queueing are presenter-owned; callbacks run on the presenter thread and do not mutate visible automatically.

Receiver
