Setting Up Flutter Internationalization with Device Language Settings

In today's globalized world, developing applications that cater to multiple languages is crucial. If you're working with a Flutter app and want to enhance its user experience by setting the default language based on the device’s language settings, you’ve come to the right place. This blog will guide you on how to implement this feature while allowing users to change their preferred language through a dropdown menu.

The Challenge
