Iako je Flutter performantan po zadanom, optimizacija performansi uključuje minimiziranje nepotrebnih rebuilda, učinkovito renderiranje listi, pravilnu upotrebu const, izbjegavanje skupih operacija u build, i profiliranje. Razumijevanje toga održava aplikacije glatke (60/120 fps).
Minimiziranje nepotrebnih rebuilda
✓ 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
