Fluid Values

BreakifyFluidValue interpolates linearly between each pair of defined breakpoint values:

const spacing = BreakifyFluidValue(
  sm: 8,
  md: 16,
  lg: 24,
);

final resolvedSpacing = context.resolve(spacing);

Before the first defined point it uses the first value; after the last it uses the last. Use resolveRounded when the result should be rounded to the nearest logical pixel.
