Worked on the flutter/flutter repository to improve the reliability of testing for hot reload and hot restart features in the Flutter framework. Addressed a persistent issue with flaky continuous integration by consolidating previously split tests into a single, unified test case, ensuring both functionalities were validated together. This approach enhanced test integrity and reduced maintenance overhead without altering production code. Utilized Dart and Flutter, focusing on targeted test-level changes to streamline the validation process. The work emphasized robust testing practices and contributed to a more stable development workflow by preventing intermittent failures and simplifying ongoing test maintenance within the project.
