DoubleExtension extension

Extension methods on double for convenient conversion to flexbox units.

This extension provides convenient getters to convert double values into various flexbox unit types such as SizeUnit, PositionUnit, and SpacingUnit. It also provides utilities for percentage calculations and relative sizing.

Example:

final size = 100.0.size;  // Creates SizeUnit.fixed(100.0)
final position = 50.0.position;  // Creates PositionUnit.fixed(50.0)
final spacing = 10.0.spacing;  // Creates SpacingUnit.fixed(10.0)
