flutter_boring_avatars 2.1.0

Boring avatars can generate unique avatars based on the username and color palette.

2.1.0

Special thanks to blopker for the performance improvements in this release!

Performance

• Marble painter: cached static paths and single-pass transforms — The two SVG-like Path objects in the marble variant had constant geometry but were rebuilt from scratch on every paint call. They are now top-level constants, created once. Additionally, the per-element transform and resize transform (previously applied as two separate Path.transform() calls, producing 4 Path allocations per frame) are now combined into a single Matrix4, halving path allocations. Benchmarked at ~2x faster paint calls.

• Widget data caching — BoringAvatar and AnimatedBoringAvatar were StatelessWidgets that called BoringAvatarData.generate() on every build(), re-running the hash function and property calculations even when inputs hadn't changed. Both are now StatefulWidgets that cache the generated BoringAvatarData and only regenerate when the resolved name, type, palette, or shape actually change. This eliminates redundant work during parent rebuilds (e.g. scrolling lists, unrelated setState calls).

• Animated paint hint — The CustomPaint inside AnimatedBoringCanvas now sets willChange: true, telling the raster cache not to waste effort caching frames that are immediately invalidated during animation.

Fixes

• Resolved all deprecated API warnings: Matrix4.translate/scale migrated to translateByDouble/scaleByDouble, Color.withOpacity to withValues, Color.red/green/blue to the new component accessors, and Color.value to toARGB32.
