In June 2025, Gourab Kumar Sinha updated the flutter/flutter repository by removing support for Android Lollipop (API levels 21-22) and raising the minimum SDK requirement to 23. This work involved cleaning up deprecated code paths and tests, streamlining the codebase for better maintainability and alignment with modern Android features. Using Java and leveraging Android development and unit testing skills, Gourab’s changes reduced technical debt and simplified future integration efforts. The update addressed compatibility issues with newer Android ecosystems, ensuring the project remains current. The scope was focused but foundational, laying groundwork for ongoing improvements in Android platform support.
