Performance Starts Before Profiling
A fast app usually begins with simple widget trees, controlled rebuilds, clear loading states, and data models that do not force the interface to guess. Profiling is important, but it works best after the structure is already clean.
Design for Real Devices
Production Flutter apps should be checked on mid-range devices, slow networks, and dense content screens. Smooth animation on a developer machine is not enough evidence for a reliable customer experience.
Keep Measurement Close
OpenStair treats performance as a release habit. We watch image sizes, app startup, API latency, rebuild hot spots, and navigation flow so quality remains visible throughout development.
