यद्यपि Flutter पूर्वनिर्धारितरूपले कार्यक्षम छ, कार्यक्षमता अनुकूलन गर्नले अनावश्यक rebuilds कम गर्ने, कुशल list rendering, const को उचित उपयोग, build मा महँगो काम टालना, र profiling समावेश गर्दछ। यी बुझ्दा अनुप्रयोगहरू smooth (60/120 fps) रहन्छन्।
अनावश्यक rebuilds कम गर्नुहोस्
✓ Use CONST constructors where possible → const widgets aren't rebuilt (huge win)
const Text('Static') // not rebuilt unnecessarily
✓ Keep setState/rebuild scope SMALL → rebuild only what changed (extract widgets so
state changes rebuild a small subtree, not the whole screen)
✓ Use targeted state management (rebuild only widgets that depend on changed state)
✓ Don't rebuild large trees for small changes
