LocaleProvider class
A provider class that manages the application's locale settings.
This class extends ChangeNotifier to provide reactive locale state management throughout the Flutter application. It handles locale persistence using SharedPreferences and ensures only supported locales are applied.
The provider initializes with a saved locale preference or defaults to the first supported locale. It provides methods to change the current locale and retrieve human-readable language names.
Example usage:
// In your widget:
Consumer<LocaleProvider>(
builder: (context, localeProvider, child) {
return Text('Current locale: ${localeProvider.locale}');
},
)
