Worked on the aau-giraf/foodplanner repository to enhance the authentication experience for mobile users. Focused on building a robust login flow using Flutter and Dart, introducing explicit input validation for missing credentials and clearer error messaging for authentication failures. Adjusted the duration and visibility of login messages to reduce user confusion and improve overall sign-in usability. Incorporated Danish language cues in the messaging, laying the groundwork for future localization and internationalization efforts. The work emphasized front end and mobile development best practices, resulting in a more intuitive and scalable authentication workflow that addresses both user experience and security considerations.
