createShader method
- @override
override
Creates a Shader for this gradient to fill the given rect.
If the gradient's configuration is text-direction-dependent, for example
it uses AlignmentDirectional objects instead of Alignment
objects, then the textDirection
argument must not be null.
Implementation
@override
Shader createShader(Rect rect, { TextDirection textDirection }) {
return ui.Gradient.sweep(
center.resolve(textDirection).withinRect(rect),
colors, _impliedStops(), tileMode,
startAngle,
endAngle,
);
}
