Animations in Flutter
summary
Covers concrete Flutter techniques: uses AnimationController with vsync and listeners, shows when to prefer AnimatedWidget (FadeTransition, SlideTransition) vs AnimatedBuilder for staggered timelines using Interval slices (e.g. 0.0–0.25) and curves like elasticOut, implements a gravity simulation for physics-based motion, and integrates Flare vector assets (Flare). Demonstrates the actual code (around 150 lines), claims smooth rendering at 60 fps on supported devices, and notes desktop/web builds work in preview while production apps (meditation app) run on low-end phones.
