scale method

@override RadialGradient scale(double factor)

Returns a new RadialGradient with its colors scaled by the given factor.

Since the alpha component of the Color is what is scaled, a factor of 0.0 or less results in a gradient that is fully transparent.

Implementation

@override
RadialGradient scale(double factor) {
  return RadialGradientPainter(
    center: center,
    radius: radius,
    colors: colors
        .map<Color>((Color color) => Color.lerp(null, color, factor)!)
        .toList(),
    stops: stops,
    tileMode: tileMode,
    focal: focal,
    focalRadius: focalRadius,
    transform: transform,
    colorSpace: colorSpace,
    density: density,
  );
}
