Flutter's Golden Age
summary
Announces an open source package called Flutter Test Goldens that replaces Golden Toolkit by producing decorated galleries, extracting per-widget snapshots, and adding a timeline feature to capture interactions and animations frame-by-frame. It embeds JSON metadata into PNGs (after a discarded QR prototype) so scenes can track bounds and gestures, and it generates consolidated failure scenes with absolute and relative diffs. Package is alpha, published as flutter test goldens on pub and documented at fluttergoldens.com.
