Style class

A utility class for managing a collection of styling attributes and variants.

The Style class is used to encapsulate a set of styling attributes and variants which can be applied to a widget. This class provides several factory constructors and utility methods to help create, manipulate, and merge collections of styling attributes and variants.

Example:

final style = Style(attribute1, attribute2, attribute3);
final updatedStyle = style.variant(myVariant);
