Elevator class
A widget that creates an elevated overlay effect when hovered.
The Elevator widget creates a hover effect by rendering its child twice: once in the normal widget tree and once in an overlay. When the user hovers over the widget, it shows the overlay version while hiding the original, creating an "elevation" effect.
The overlay version is automatically clipped to stay within any scrollable parent's viewport, supporting both vertical and horizontal scrolling.
Example usage:
Elevator(
builder: (elevated) => Container(
decoration: BoxDecoration(
boxShadow: elevated ? [BoxShadow(...)] : null,
),
child: YourContent(),
),
)
The builder function is called with a boolean indicating whether the widget is currently elevated, allowing you to modify the appearance based on the elevation state.
