is there something like?:
public static final Locale APP_LOCALE = Locale.GERMAN;
Operating system and browser locale are all in German but Vaadin UI DatePicker and Core-Buttons are still English
Translation or Internationalization is not intended.
HTML-Source is show correct;
<!doctype html><html lang="de">
Resources I found are all very old and do not work for Vaadin Flow
Thanks for any advice!
the magic is done with the I18NProvider. You should implement this interface and activate it. In a component get the translations with getTranslation(..). For detailed examples read the i18n tutorial : https://vaadin.com/tutorials/i18n or ping me ;)
