Flutter Performance Optimization: Challenges, Tools, and Best Practices

The Xianyu team’s talk outlines Flutter performance challenges—complex list‑item logic, a 16.6 ms frame budget, DynamicX template overhead, and scroll‑curve‑induced offset jumps—and presents best‑practice solutions such as PowerScrollView caching, partial refresh, frame‑splitting, DynamicX caching, isolate offloading, layer merging, plus custom benchmarking, DevTools extensions, and FlutterBlockCanary for measurement, urging developers to prioritize perceived smoothness, monitor raster costs, and leverage multi‑threading and community updates.
