)
const val TOAST_ID_LOADING = ANYTHING
toaster.show(message = "Loading", id = TOAST_ID_LOADING, duration = Duration.INFINITE)
toaster.show(message = "Success", id = TOAST_ID_LOADING)
toaster.dismiss(id)
toaster.dismiss(toast)
toaster.dismissAll()
// Enable close buttons
Toaster(
state = toaster,
showCloseButton = true,
)
// Set an action button
toaster.show(
message = "Message",
action = TextToastAction(
text = "Dismiss",
onClick = { toaster.dismiss(it) },
)
)
Toaster(
state = toaster,
iconSlot = { toast ->
// ICON_LOADING can be anything, it's just a mark
if (toast.icon == ICON_LAODING) {
LoadingIcon()
} else {
// Fallback to the default icon slot
ToasterDefaults.iconSlot(toast)
}
},
)
Toaster(
state = toaster,
dismissPause = ToastDismissPause.[Never | OnNotFront | OnInvisible],
)
Define the mapping function
fun UiMessage.toToast(): Toast = when (this) {
is UiMessage.Error -> Toast(id = id, message = message, type = ToastType.Error)
is UiMessage.Success -> Toast(id = id, message = message, type = ToastType.Success)
}
Then
val toaster = rememberToasterState(
onDismissed = { viewModel.removeUiMessageById(it.id as Long) },
)
val uiState by viewModel.uiState.collectAsState()
LaunchedEffect(viewModel, toaster) {
// Listen to messages changes and map to toasts
val toastsFlow = viewModel.uiState.map { it.uiMessages.map(UiMessage::toToast) }
toaster.listenMany(toastsFlow)
}
Toaster(state = toaster)
Or use an adapter function
