JetPack Compose Performance Tips & Tricks
summary
Explains concrete fixes: use remember to avoid rerunning logic every frame, use derivedStateOf to collapse thresholds (only change when crossing 20 likes), give Lazy lists stable keys (IDs) to prevent full-list recomposition, defer state reads into layout or draw lambdas to skip composition work, enable R8 and baseline profiles for big performance wins, run the compose compiler metrics plugin and mark collections immutable or annotate/wrap models so composables become skippable.
