Key insights:
CustomPainter Basics: Use size-relative coordinates, reuse Paint objects, and implement shouldRepaint to limit redraws.
Drawing AR-Like Overlays: Compose reticles, rings, labels, and images with simple canvas calls and gradients for convincing effects.
Animating Effects With Canvas: Drive painters with AnimationController or tick updates, compute values outside paint, and avoid allocations in paint.
Optimizations For Mobile: Reuse resources, clip off-screen work, raster-cache static layers, and profile with DevTools to maintain frame rates.
