generateAndSaveLocalizations static method

Future<void> generateAndSaveLocalizations({ required String enAssetPath, required List<String> targetLanguages, required String outputDirectory, dynamic onProgress(String language, String status)?, int delayBetweenTranslations = 200, })

Generates and saves localization files from English source - 100% FREE

enAssetPath - Asset path to the English JSON file (e.g., 'assets/l10n/en.json') targetLanguages - List of language codes (e.g., 'ar', 'de', 'fr', 'es') outputDirectory - Directory where translation files will be saved (e.g., 'assets/l10n') onProgress - Optional callback to track progress delayBetweenTranslations - Delay in milliseconds between translations (default: 200ms)

Generates translations and automatically saves them to disk
