MyLoadingEffect class
A widget that applies a shimmer effect animation to its child.
This widget wraps a child widget and adds a shimmering effect that moves from topLeft to bottomRight, useful for indicating loading states. The shimmer effect is applied as an overlay on the child widget, preserving its content. The colors adapt to the theme's brightness (light or dark mode).
