FlexSchemeColor.from constructor

FlexSchemeColor.from({ required Color primary, Color? primaryVariant, Color? secondary, Color? secondaryVariant, Color? appBarColor, Color? error, })

Implementation

factory FlexSchemeColor.from({
  required Color primary,
  Color? primaryVariant,
  Color? secondary,
  Color? secondaryVariant,
  Color? appBarColor,
  Color? error,
}) {
  return FlexSchemeColor(
    primary: primary,
    // ignore: avoid_redundant_argument_values
    primaryVariant: primaryVariant ?? primary.darken(kDarkenPrimaryVariant),
    secondary: secondary ?? primary.darken(kDarkenSecondary),
    secondaryVariant: secondaryVariant ??
        // ignore: avoid_redundant_argument_values
        secondary?.darken(kDarkenSecondaryVariantFromSecondary) ??
        primary.darken(kDarkenSecondaryVariant),
    appBarColor: appBarColor ??
        // ignore: avoid_redundant_argument_values
        secondary?.darken(kDarkenSecondaryVariantFromSecondary) ??
        primary.darken(kDarkenSecondaryVariant),
    // Accent color defaults to primary if not defined.
    // accentColor: accentColor ?? primary,
    error: error,
  );
