gen_i18n 1.0.3

Library to help you add internationalization in your project dart generating classes and translation files.

gen_i18n

Add internationalization to your dart project

Installation

dependencies:
    flutter_localizations:
        sdk: flutter 

dev_dependencies:
    gen_i18n: ^1.0.3

flutter: 
  assets:
    - assets/i18n/locale/

Usage

Running this command will result in the creation of the following files:

• i18n.dart : a dart file will be generated in lib/i18n/. This dart file will be responsible for interpreting the translation files

{
  "customMessage": "Write is here your message"
}

• locale : directory where the translation files live. They will be generated in the folder assets/i18n/locale

Note: The name of a translation file starts without the key i18n_ example: i18n_en.json

flutter pub run gen_i18n:initialize

Supported arguments:

Argument	Description
--locale	By definition only one translation file is generated i18n_en.json. If you want to create more translation files for other languages just send the arguments. Example: flutter pub run gen_i18n:initialize --locale-pt-es

Example

Modifies the main method

Future<void> main() async {
  /// This is required
  WidgetsFlutterBinding.ensureInitialized();
  
  /// Initial locale is critical to initializing the internationalization feature
  await I18n.initialize(
      defaultLocale: Locale('en'),   /// This is required
      supportLocales: [Locale('en'),Locale('es')]  /// This is optional
  );
  ...
}

MaterialApp( 
      locale: I18n.currentLocate,
      supportedLocales: I18n.supportedLocales,
      localizationsDelegates: const [
        const I18nDelegate(),
        GlobalMaterialLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate
      ],
      ...
    )

To translate text, simply enter the key by calling the method I18n.getValue('customMessage') or 'customMessage'.translate

Text(I18n.getValue('customMessage'))

Text('customMessage'.translate)

If you want to change the current locate simply call the await I18n.updateLocate(Locale('es')) method.
