This Component is intended for Vaadin 14 Applications that use an [I18NProvider](https://vaadin.com/docs/v14/flow/advanced/tutorial-i18n-localization.html). It is a Language Picker based on the `Select` component from Vaadin. Changing the Language with this component will automatically set a new Locale in the VaadinSession and all UI's that belong to that Session. It will trigger the `localeChange(LocaleChangeEvent event)` function of every opened View that implements `LocaleChangeObserver`, so that any translated labels and strings can be re-translated in the new language and replaced in the View without reloading. You can now also choose to set a language cookie upon value change, so you can manually set the Session Locale to the used Locale upon Session-Init. See Code Samples for how to do that. Using the Constructor without a boolean parameter will NOT set language cookies upon value change. --------- LANGUAGE FLAGS: You need to provide a flag image for each Locale/Language that you will add as item. Place these images in `img/languageflags/` folder, and name them [language_code].png For example en.png for english flag. To find out where the `img` folder should be, see https://stackoverflow.com/questions/57553973/where-should-i-place-my-vaadin-10-static-files It will either be `/src/main/webapp/img` or `/src/main/resources/META-INF/resources/img` Warning: if using Spring Security, you need to ignore '/img/**' in your `WebSecurityConfigurerAdapter::configure(WebSecurity web)`. I will fix that in next version by using /images folder instead of /img. TRANSLATIONS OF LANGUAGE NAMES: In the ResourceBundle that your I18NProvider implementation uses, add Translations for each Locale/Language that you will use. The keys must be named `LanguageSelect.[language_code]` For example `LanguageSelect.en=English` in the English resourcebundle-file, and `LanguageSelect.en=Inglés` in the Spanish resourcebundle-file
