+///Documentation
+/// A unified loading indicator widget with multiple variants and customization options
+/// This widget provides consistent loading states across the entire app with
+/// support for different variants, sizes, colors, and text labels.
+/// Usage:
+/// ```dart
+/// CoreLoadingIndicator(
+///   variant: CoreLoadingVariant.material,
+///   size: CoreLoadingSize.medium,
+///   color: Colors.blue,
+///   label: 'Loading...',
+/// )
+/// ```
+/// or use predefined constructors:
+/// ```dart
+/// CoreLoadingIndicator.small(color: Colors.red)
+/// CoreLoadingIndicator.cupertino(size: CoreLoadingSize.large)
+/// CoreLoadingIndicator.linear(value: 0.5)
+/// CoreLoadingIndicator.lottie(size: CoreLoadingSize.extraLarge, label: 'Please wait')
+/// ```
+/// or show a full-screen overlay:
+/// ```dart
+/// CoreLoadingOverlay.show(context)
+/// ```
+/// or hide the overlay:
+/// ```dart
+/// CoreLoadingOverlay.hide(context)
+/// ```
+/// Parameters:
+/// - variant: The type of loading indicator (material, cupertino, linear, lottie
+/// - size: Preset sizes (small, medium, large, extraLarge)
+/// - width, height: Custom dimensions (overrides size preset)
+/// - color: Color of the indicator
+/// - value: Progress value for determinate indicators (0.0 to 1.0
+/// - strokeWidth: Stroke width for circular indicators
+/// - label: Optional text label below the indicator
+/// - labelStyle: Text style for the label
+/// - labelSpacing: Spacing between indicator and label
+/// - labelAlignment: Alignment of the label relative to the indicator
+/// - backgroundColor: Background color for overlay
+/// - barrierDismissible: Whether the overlay blocks user interaction
+/// Note: Requires `lottie` package for Lottie animations
+/// Example Lottie asset can be found in `assets/animations/loading.json`
+/// Make sure to add it to your pubspec.yaml
+/// ```yaml
+/// assets:
+///  - assets/animations/loading.json
