scale method
- double factor
override
Returns a new SweepGradient 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
SweepGradient scale(double factor) {
return SweepGradient(
center: center,
startAngle: startAngle,
endAngle: endAngle,
colors: colors.map<Color>((Color color) => Color.lerp(null, color, factor)!).toList(),
stops: stops,
tileMode: tileMode,
);
}
