SliderValue class

Represents a slider value, supporting both single and range configurations.

A SliderValue can represent either a single point value or a dual-thumb range with start and end values. Use SliderValue.single for single-thumb sliders and SliderValue.ranged for range sliders.

This class provides value interpolation, division rounding, and comparison operations needed for slider animations and discrete value snapping.

Example:

// Single value slider
final single = SliderValue.single(0.5);
print(single.value); // 0.5

// Range slider
final range = SliderValue.ranged(0.2, 0.8);
print(range.start); // 0.2
print(range.end);   // 0.8
