Worked on the ankidroid/Anki-Android repository to optimize the Card Browser refresh process by introducing OpChanges in place of the manual reloadRequired flag. This refactor streamlined the refresh logic, removing manual state management and thereby improving both performance and maintainability. By leveraging Kotlin and Android development skills, the update reduced the risk of bugs associated with manual refresh state handling and established a foundation for an OpChanges-driven workflow. The work focused on enhancing the reliability and clarity of the Card Browser’s refresh mechanism, resulting in a cleaner codebase and a more robust approach to managing UI state changes within the application.
