Hope this helps to understand how localization works in Flutter, how to get current values, and how to reflect system changes. Hey gang, in this Flutter tutorial for beginners, Ill give you a quick introduction to the course and Flutter itself, a preview of what well be building &. Now you can see that the ru locale was selected as the app locale. Now let's change the settings to the Russian language as the default system value:

The supported locales are defined without country codes to show you how the selection of the current app locale works. To use it, you must call this expression in a child component's build method. Obviously, if your app widget is not initialized, you can not get its locale.

You can not use it before the MaterialApp initialization. This works only when the MaterialApp widget is already initialized. Getting your application locale final Locale appLocale = Localizations.localeOf(context) When you request an application locale you will get an exact value from the list of supportedLocales. Providing delegates is required if your app supports any other locales except en_US. That means you should explicitly define them in the widget initialization in the supportedLocales property and provide so-called "localization delegates" that will do the actual translation to a selected locale (the localizationsDelegates property). It accepts the list of locales that you decided your app supports. The MaterialApp widget supports localization.
