xsoulspace_locale 0.0.1

Unified locale wrapper to make localization easier.

UI Locale Package

This package provides a flexible and easy-to-use localization solution for Flutter applications. It allows you to manage multiple languages, keyboard languages, and localized strings efficiently.

Features

• Support for multiple languages: Manage multiple languages for your application.
• Dynamic locale switching: Dynamically switch between locales at runtime.
• Keyboard language management: Manage keyboard languages for different locales.
• Localized string management: Manage localized strings for different languages.

Setup

Step 1: Add the package to your pubspec.yaml

dependencies:
  ui_locale: ^0.0.1

Step 2: Import the package in your Dart code

import 'package:ui_locale/ui_locale.dart';

Step 3: Initialize the LocalizationConfig

You can initialize the LocalizationConfig at the start of your application or in any widgets before using MaterialApp or CupertinoApp.

void main() {
  final languages = (
    en: UiLanguage('en', 'English'),
    es: UiLanguage('es', 'Español'),
    fr: UiLanguage('fr', 'Français'),
  );

  LocalizationConfig.initialize(
    LocalizationConfig(
      supportedLanguages: [
        languages.en,
        languages.es,
        languages.fr,
      ],
      fallbackLanguage: languages.en,
    ),
  );


  // Now you can use KeyboardLanguage like this:
  final englishKeyboard = KeyboardLanguage.fromLanguage(languages.en);
  final spanishKeyboard = KeyboardLanguage.fromLanguage(languages.es);
  final allKeyboardLanguages = KeyboardLanguage.values;
  final defaultKeyboard = KeyboardLanguage.defaultKeyboardLanguage;

  runApp(MyApp());
}

Usage

Locale Management

Use LocaleLogic to manage locale changes:

class MyApp extends StatefulWidget {
  @override
  MyAppState createState() => _MyAppState();
}

class MyAppState extends State<MyApp> {
  final LocaleLogic localeLogic = LocaleLogic();
  Locale currentLocale = Locales.fallback;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      locale: currentLocale,
      localizationsDelegates: [
        // Your localization delegates
      ],
      supportedLocales: LocalizationConfig.instance.supportedLocales,
      home: MyHomePage(),
    );
  }

  Future<void> changeLocale(Locale newLocale) async {
    final result = await localeLogic.updateLocale(
      newLocale: newLocale,
      oldLocale: currentLocale,
      uiLocale: currentLocale,
    );
    if (result != null) {
      setState(() {
        currentLocale = result.uiLocale;
      });
    }
  }
}

Localized Strings

To manage localized strings, use the LocalizedMap class. Here's an example of how to create a LocalizedMap and retrieve a localized string based on the current locale:

final localizedString = LocalizedMap(
  value: {
    languages.en: 'Hello',
    languages.es: 'Hola',
    languages.fr: 'Bonjour',
  },
);

// Retrieve the greeting based on the current locale
String greeting = localizedString.getValue(context.locale);

Keyboard Language

For managing keyboard languages, use the KeyboardLanguage class. Here's an example of how to get the current keyboard language based on the current locale:

// Get the current keyboard language based on the current locale
final currentKeyboardLanguage = KeyboardLanguage.defaultKeyboardLanguage;
// or
final currentKeyboardLanguage = KeyboardLanguage.fromLanguage(
  UiLanguage.byLocale(context.locale),
);

Best Practices

1. Initialize LocalizationConfig: Always initialize LocalizationConfig before using any other classes from this package.
2. Use LocaleLogic for locale changes: Use LocaleLogic to handle locale changes and ensure proper updates across your app.
3. Manage localized strings with LocalizedMap: Utilize LocalizedMap for managing strings that need to be localized.
4. Consider KeyboardLanguage for input methods: Consider using KeyboardLanguage when dealing with input methods that may vary by language.
5. Update supported languages and locales: Regularly update your supported languages and locales in the LocalizationConfig as your app expands to new regions.

Note

This package is designed to work alongside Flutter's built-in localization system. It provides additional functionality for managing locales and localized content but does not replace Flutter's Localizations widget or localization delegates.
