In the context of international deployment, how do you handle localization and multilingual support in a Flutter app?

Using a combination of 'Intl' and 'arb' files for dynamic localization is a best practice in Flutter for handling internationalization. 'Intl' is a library for internationalization and localization that allows developers to manage translations efficiently. 'arb' files (Application Resource Bundle) are used to store translations, making it easy to manage and update localized content. This approach ensures maintainability and scalability when supporting multiple languages in a Flutter app.
