NxBackgroundCard class

A customizable card widget that sizes itself relative to the screen dimensions.

This widget wraps Flutter's Card widget and adds convenient sizing functionality by allowing height and width to be specified as fractions of the screen size. It also provides common customization options like elevation, shape, and scrolling.

Example usage:

NxBackgroundCard(
  height: 0.5, // Takes up half the screen height
  elevation: 20,
  child: Column(
    children: [
      Text('Card Content'),
      // ... other widgets
    ],
  ),
)

The card automatically applies rounded corners at the top edges by default, making it suitable for bottom-sheet style interfaces when positioned at the bottom of the screen.
