Skill UI

Practical guide for pre-caching fonts, images, animations, and initial data in Flutter and Flutter Web to reduce jank, font swaps, and startup delays. Covers Google Fonts, asset/network images, multiple image preloading, and app-start preloader patterns.

This skill provides a rigorous, structured method for inspecting animated 3D characters, rigs, and motion retargeting in Blender. It moves beyond visual evidence (screenshots) by extracting and comparing structured data points such as bone transformations, bounding box changes, ground contacts, and axis conventions. Ideal for diagnosing subtle animation flaws like foot sliding, ground penetration, or incorrect orientation that are invisible in still images.
