Annotation Type Theme

@Target(value=TYPE)
 @Retention(value=RUNTIME)
 @Inherited
 @Documented
public @interface Theme

Defines that there is a theme to use and defines the theme handler implementation.

The theme allows to define a way to translate base component url to the themed component url (@see AbstractTheme), which specifies components styles.

By default com.vaadin.flow.theme.lumo.Lumo theme is used if it's in the classpath. You may disable theming with NoTheme annotation.

Theme annotation should be added to the AppShellConfigurator implementation.

Only a single theme can be defined and having multiple instances will throw an exception.

Here is an example:

 

 @Theme(Lumo.class)
 public class MyAppShell implements AppShellConfigurator {
 }
