Performance Optimization of Xianyu Flutter App: Smoothness, Load Time, and Rendering Improvements
The Xianyu team optimized their Flutter‑based app by creating a lag‑diagnosis tool, minimizing unnecessary widget rebuilds, deferring load‑more updates, using low‑resolution placeholders, prefetching data with skeleton screens, reusing FlutterBoost containers and early data passing, which together cut jank by half, shaved ~300 ms off page loads and raised average FPS by about three points on low‑end devices.
