 ### How to change the language dynamically at runtime?
 This plugin uses the native capabilities of each platform, language selection is therefore made by the OS.
-There is no plan to implement this feature in the near future.

+import { overrideLocale } from "nativescript-localize/localize";
+const localeOverriddenSuccessfully = overrideLocale("en-GB"); // or "nl-NL", etc
