During a two-month period, H. Batagelo focused on enhancing the stability and reliability of Windows multi-window scenarios in the engine-flutter-autoroll/flutter repository. He addressed a critical crash by validating view IDs before invoking key event callbacks, preventing use-after-free errors during window shutdown flows. Batagelo reinforced this fix with targeted unit tests to guard against regressions. In the flutter/flutter repository, he implemented explicit multi-view cursor management, decoupling cursor handling from implicit view assumptions and improving cursor rendering accuracy. His work, primarily in C++ and Flutter with a strong emphasis on unit testing, demonstrated careful attention to robust input handling and test coverage.
