NxEmptyScreen class

A widget that displays an empty state with an icon and message.

This widget is useful for showing placeholder content when there is no data to display, or when a feature is not yet implemented. It shows a centered icon (defaulting to a sad face) with a message below it.

The widget can be customized with different colors, icons, and dimensions, and automatically adapts to the screen size if no specific dimensions are provided.

Example usage:

NxEmptyScreen(
  context: context,
  information: Text('No items found'),
  color: Colors.grey[100],
  icon: Icons.inbox_outlined,
  height: 300,
)
