curveCardinalTension function Curves
Returns a cardinal curve with the specified tension
in the range [0, 1].
The tension
determines the length of the tangents: a tension
of one
yields all zero tangents, equivalent to curveLinear; a tension
of zero
produces a uniform Catmull–Rom (see curveCatmullRom) spline. For example:
final line = Line(…)..curve = curveCardinalTension(0.5);
Implementation
CurveCardinal Function(Path) curveCardinalTension(num tension) {
return (context) => CurveCardinal(context, tension);
}
