Month: 2026-04 — Lynx platform: Delivered cross-platform scrolling enhancements and robust edge-case handling in lynx. Key features delivered include the Enhanced Scrolling Experience: Android Nested Scrolling Edge Handling and Cross-Platform Scroll Info, adding scrollX, scrollY, and maxScrollOffset to getScrollInfo while preserving iOS legacy scrollRange for compatibility across Clay/Android/iOS/Harmony. Major bugs fixed include allowing the nested scrolling parent to takeover on edge non-touch nested flings to extend the available scroll range, and aligning maxScrollOffset across platforms by computing max(contentSize - viewportSize, 0). These changes are backed by commits 43ef0c857966180042e30133df0fc37e773aa114 and 184f6da2956bb8b9523c006bba21f8f3c9dfd8a2. Overall impact: delivers a consistent, smoother scrolling experience across platforms, reduces edge-case regressions, and strengthens cross-platform scrolling APIs for long lists. Technologies/skills demonstrated: Android nested scrolling semantics, cross-platform API design, getScrollInfo enhancements, platform-agnostic performance considerations, and Git-based collaboration.
