Reduce Flutter UI rebuilds by converting eligible widgets to const, preferring StatelessWidget over StatefulWidget, and avoiding heavy work in the build() method to improve app smoothness.

High memory usage in Flutter often stems from inefficient image handling and unoptimized lists. Apply ListView.builder with itemExtent and cache images to minimize resource consumption.

Optimize image-heavy Flutter interfaces by applying image caching, preloading images, and using RepaintBoundary to limit unnecessary redraws and reduce jank.

Yes, you can use ListView.builder with itemExtent and RepaintBoundary to minimize rebuilds and layouts in Flutter, effectively limiting redraws and improving list scrolling performance.

Use const widgets during Flutter development to avoid unnecessary rebuilds. Converting eligible widgets to const prevents the framework from recalculating them, directly improving rendering performance.
