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,
)
