Do we need to create a UI class in Vaadin?

<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-spring-boot-starter</artifactId>
</dependency>

SpringBoot 2 Vaadin 12.0.3

@Route("")
public class IndexView {

I followed a video tutorial and the above example seems to work just fine. I don't have any xyz extends UI class. When I hit localhost, I see my Index View rendered.

But other recent examples I see online show something like Main extends UI.

Is a UI class necessary? If so, which UI should be imported. Examples show com.vaadin.ui.UI while the only UI class I see in the class path is com.vaadin.flow.component.UI.

No, extending UI is no longer necessary in Vaadin 10+. Any component with @Route("") will be the root component.
