Performance

Priority: P1 (OPERATIONAL)

• Rebuilds: Use const widgets and buildWhen / select for granular updates.
• Lists: Always use ListView.builder for item recycling.
• Heavy Tasks: Use compute() or Isolates for parsing/logic.
• Repaints: Use RepaintBoundary for complex animations. Use debugRepaintRainbowEnabled to debug.
• Images: Use CachedNetworkImage + memCacheWidth. precachePicture for SVGs.
• Keys: Provide ValueKey for list items and stable IDs for reconciliation.
• Resource Cleanup: Dispose controllers/streams in dispose().
• Pagination: Default to 20 items per page for network lists.
• Build Purity: Keep build methods free of heavy work; move logic to BLoC/Application.
• Image Resizing: Always set maxWidth/maxHeight when loading images.
