colorList method
Provide a required color
from which this
Curvature may generate a
corresponding List<Color>
. The depth
of the effect is a required
int. A lower depth
fades the object more into its background, while
a larger one will set the object more apart by contrast.
Implementation
List<Color> colorList(
Color color, {
required Swell swell,
required int depth,
}) {
final _color = swell.toColor(color, depth);
switch (this) {
case Curvature.superconcave:
return [
_color.withBlack((depth * 1.5).round()),
_color,
_color.withWhite((depth * 1.5).round()),
];
case Curvature.concave:
return [
_color.withBlack(depth),
_color,
_color.withWhite(depth),
];
case Curvature.flat:
return [_color, _color, _color];
case Curvature.convex:
return [
_color.withWhite(depth),
_color,
_color.withBlack(depth),
];
case Curvature.superconvex:
return [
_color.withWhite((depth * 1.5).round()),
_color,
_color.withBlack((depth * 1.5).round()),
];
}
