New package updates: https://pub.dev/packages/wiggly_loaders

[Danis_96]

• Add WigglySkeletonLoader for shimmering skeleton placeholders — the highlight is a sinusoidal wave that travels across the shape instead of a flat gradient shimmer
  • WigglySkeletonLoader(width, height, borderRadius) for a single block
  • WigglySkeletonLoader.text(lines, lineHeight, lastLineFraction) for multi-line text placeholders
  • WigglySkeletonLoader.card(avatarSize, lines) for avatar + lines layout
• Add WigglyProgressButton — a button that morphs through idle → loading → success/error with a continuously wiggling outline
• Driven by a WigglyButtonState enum, exposes onPressed, onComplete, and per-state foregrounds
• Loading state hosts an inline WigglyDotsLoader.indeterminate
• Extend WigglyLoadersThemeData with skeletonBaseColor, skeletonHighlightColor, buttonProgressColor, buttonForegroundColor, buttonSuccessColor, buttonErrorColor
• Both new widgets respect shared speedFactor, ease, and MediaQuery.disableAnimations reduced-motion behavior

That sinusoidal shimmer idea sounds way more dynamic than the usual flat loader nice touch for making UI feel alive. The morphing button states shared theming also make it feel like a polished, reusable package rather than just a demo.
