Worked on the flutter/flutter repository to enhance interactive state management for ListTile components, focusing on RadioListTile, CheckboxListTile, and SwitchListTile. Introduced WidgetStatesController support to unify and streamline state handling, which improved UI consistency and accessibility readiness across these common form controls. The implementation, written in Dart and leveraging Flutter’s UI development and widget testing capabilities, addressed a core framework issue and aligned with ongoing pull requests. This contribution reduced the potential for bugs, facilitated future enhancements, and established a more predictable foundation for state-driven UI in forms and lists, demonstrating careful attention to maintainability and cross-team collaboration.
