NoUi Field: NoUiField is a lightweight generic field that you can use to hold back-end values that still need to be bound via com.vaadin.flow.data.binder.Binder.
NoUiCollectionField is a similar field for generic Collections. Useful when you want to manipulate a collection of associated entities in the context of Binder.
You can use both of these with the Binder class just like other fields.
