Configuration

RfsConfig controls the scaling curve.

Setting	Default	Purpose
`baseValue`	`20`	Values at or below this magnitude stay fixed
`breakpoint`	`1200`	Extent at which values reach their maximum
`factor`	`10`	Controls the derived minimum when `min` is omitted
`enabled`	`true`	Returns every maximum unchanged when disabled

Configure one calculation

dart

final value = Rfs.value(
  64,
  width: 600,
  config: const RfsConfig(
    baseValue: 16,
    breakpoint: 1000,
    factor: 8,
  ),
);

Wrap a section—or the complete app—in RfsScope:

dart

RfsScope(
  config: const RfsConfig(baseValue: 16, breakpoint: 1000),
  dimension: RfsDimension.shortestSide,
  child: MaterialApp(...),
)

Scope-aware widgets, RfsTypography.of, and context-based resolution inherit these settings. Explicit arguments always win.

Typed values do not have a BuildContext; pass a configuration and dimension explicitly when resolving them directly.

RfsEnabled toggles scaling without replacing the surrounding curve settings:

dart

RfsEnabled(
  enabled: false,
  child: pixelPerfectChart,
)

This is useful for golden tests and for UI regions that must keep fixed values.
