During February 2026, Daniel Caldas developed a dynamic error widget refresh mechanism for the NIAEFEUP/uni repository, focusing on improving user interface responsiveness and error state clarity. He implemented this feature using Flutter and Dart, leveraging state management techniques to ensure that error content remained current and reduced the risk of stale information. By aligning the ExamNotifier with the profile provider and modularizing the refresh logic, Daniel enhanced layout consistency and maintainability across the application. Although the work was scoped to a single feature, it demonstrated thoughtful engineering depth and established a solid foundation for future UI and state management enhancements.
