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() {
    localizationsDelegates: [
      // ... more localization delegates

Usage #

Getting a locale's name #

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

Example: On a device whose locale is English (en)

print(LocaleNames.of(context).nameOf('en_GB'));   // English (United Kingdom)

// If the locale isn't supported
print(LocaleNames.of(context).nameOf('zzzz'));     // English

// If the locale is invalid, but a match can be found
print(LocaleNames.of(context).nameOf('es_ZZZ'));  // Spanish

Example: On a device whose locale is French (fr)

print(LocaleNames.of(context).nameOf('en_GB'));   // anglais (Royaume-Uni)

// If the device locale isn't supported
print(LocaleNames.of(context).nameOf('zzzz'));     // français

// If the locale is invalid, but a match can be found
print(LocaleNames.of(context).nameOf('es_ZZZ'));  // espagnol

Note: If a device's locale isn't supported, English (en) names are returned.

Getting all locale names, sorted #



Getting all native locale names #


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 ... }

import 'package:flutter/material.dart';

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).

        // is not restarted.

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.

  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.

        // in the middle of the parent.

          // Column is also a layout widget. It takes a list of children and
          // arranges them vertically. By default, it sizes itself to fit its
          // children horizontally, and tries to be as tall as its parent.

          // "Toggle Debug Paint" action from the Flutter Inspector in Android
          // Studio, or the "Toggle Debug Paint" command in Visual Studio Code)
          // to see the wireframe for each widget.
          // Column has various properties to control how it sizes itself and
          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
