Developed Windows multi-display support for the flutter/flutter repository by introducing a DisplayMonitor class that retrieves and manages display properties such as size, refresh rate, and DPI. This feature enables robust multi-monitor user experiences by allowing the application to respond dynamically to display changes, reducing layout issues and flicker. The implementation leveraged C++ for Windows API integration and utilized Flutter platform channels to bridge native and Dart code, with a focus on performance and stability. Unit testing ensured reliability, and the groundwork was laid for future display-related enhancements, strengthening the display data model and improving workflows for multi-monitor environments.
