What problem does it solve?
This skill performs a focused audit of Flutter widget trees to identify rebuilds, layout cost, and rendering bottlenecks that cause jank and dropped frames. It guides optimization without modifying source code.
Core Features & Use Cases
- Rebuild analysis: detect large rebuild surfaces and opportunities for scope-limited widgets.
- Layout cost evaluation: highlight expensive layout patterns (intrinsic sizing, nested wrappers) and scrolling pitfalls.
- Rendering stability checks: flag implicit saveLayer triggers and opportunities for compositing isolation.
Quick Start
Run a UI performance audit on the provided Flutter project to generate a structured report.
