[notification] Utility method for creating notification with action button

[manolo]

Something like: Vaadin.Notification.createAction('Foo Bar Baz', callback)

Related with vaadin/vaadin-notification#18

Any news on this? A dismissible notification is a very common use case. Here's a workaround code snippet:

Code

Notification notification = new Notification();      
notification.addThemeVariants(NotificationVariant.LUMO_PRIMARY);
notification.setPosition(Notification.Position.TOP_CENTER);

HorizontalLayout notificationContent = new HorizontalLayout(
    new Label("Horizontal layout with a label with some misc text and "
        + "a Vaadin icon with a click listener to close the notification."),
    new Button(VaadinIcon.CLOSE_SMALL.create(), e -> notification.close())
);
notificationContent.setAlignItems(Alignment.CENTER);

notification.add(notificationContent);
notification.open();

The special case for dismiss button is cover in vaadin/web-components#438

But we might still want another convenience API for adding an action button, for example, an “Undo” button, in addition to the dismiss button.
