scale method Null safety
- double factor
Returns a new SweepSteps with its colors scaled by the given factor.
Since the alpha channel is what receives the scale factor,
0.0 or less results in a gradient that is fully transparent.
@override SweepSteps scale(double factor) => copyWith( colors: colors .map<Color>((Color color) => Color.lerp(null, color, factor)!) .toList(), );
