ContrastRule constructor

const ContrastRule({
  1. A11yContrastLevel level = A11yContrastLevel.aa,
  2. double? minimumRatio,
})

minimumRatio, if set, overrides the WCAG-derived threshold for every text size — the hook for teams enforcing a brand contrast minimum stricter than WCAG.

Implementation

const ContrastRule({this.level = A11yContrastLevel.aa, this.minimumRatio});
