flutter_localized_locales

flutter_localized_locales is a Flutter plugin which enables obtaining localized locale names from locale codes (ISO 639‑2 and ISO 639-3) for 563 locales.

This package is based on the flutter_localized_countries package. Data is taken from https://github.com/umpirsky/locale-list.

Getting started

Adding the localizations delegate

This package bundles required assets and provides a LocalizationsDelegate for loading them.

import 'package:flutter_localized_locales/flutter_localized_locales.dart';

void main() {
  runApp(MaterialApp(
    localizationsDelegates: [
      LocaleNamesLocalizationsDelegate(),
      // ... more localization delegates
    ],
    ...
  );

Usage

Getting a locale's name

LocaleNames.of(context).nameOf(String locale)

// Invalid locale string
print(LocaleNames.of(context).nameOf('zzzzz'));    // null

// On a device whose selected locale is English (en)
print(LocaleNames.of(context).nameOf('fr_CA'));   // French (Canada)

// On a device whose selected locale is Spanish (es)
print(LocaleNames.of(context).nameOf('fr_CA'));   // francés (Canadá)

// On a device whose selected locale isn't supported, an attempt is made to find a matching locale
// e.g. for a device whose locale is German (United Kingdom), returns German (de) names
print(LocaleNames.of(context).nameOf('fr_CA'));   // Französisch (Kanada)

// Otherwise, English (en) names are returned. 
// You can specify a different fallback locale with
LocaleNamesLocalizationsDelegate(fallbackLocale: 'fr')

Supported locales are listed in lib/locales.dart.

Getting all locale names, sorted

LocaleNames.sortedByCode()

LocaleNames.sortedByName()

Getting all native locale names

LocaleNames.nativeLocaleNames

For convenience, this package provides a map of locale codes to native locale names. This always returns the same data, irrespective of the device locale.

print(LocaleNames.nativeLocaleNames);      // { ... af_ZA: Afrikaans (Suid-Afrika), ... ar: ال العربية السعودية) ...  as: অসমীয়া ... fr: Français ... en: English ... }

Known Bugs

Sorting by name does not respect the locale, because Flutter does not provide any API for string collation.
