Worked on enhancing the firebase/flutterfire repository by delivering advanced Android features for the Firebase Database FlutterFire plugin. Focused on expanding the keepSynced modifiers and introducing new query capabilities such as orderBy and cursor, the work improved data synchronization reliability and query flexibility for Android applications. Utilized Dart and Kotlin to implement these enhancements, while also increasing test coverage to ensure stability and prevent regressions. Addressed integration and CI workflow by refining formatting and test processes, including adjustments for web compatibility. These contributions enabled more flexible and reliable data querying and synchronization, improving user experience and aligning feature parity across platforms.
