Flutter Skeletonizer Engineering

Mission

Build skeleton loading that improves perceived responsiveness without corrupting state semantics, accessibility, interaction safety, layout stability, or frame performance. Use this governing model:

user operation
→ classify loading phase
→ decide whether skeleton is appropriate
→ preserve final geometry
→ keep fake data presentation-only
→ suppress unsafe interaction + fake semantics
→ replace/defer expensive descendants
→ choose theme/motion-aware effect
→ test loading transitions
→ profile on representative hardware
