transform method
- @override
override
Returns the value of the curve at point t
.
The value of t
must be between 0.0 and 1.0, inclusive. Subclasses should
assert that this is true.
A curve must map t=0.0 to 0.0 and t=1.0 to 1.0.
Implementation
@override
double transform(double t) {
assert(t >= 0.0 && t <= 1.0);
assert(threshold >= 0.0);
assert(threshold <= 1.0);
if (t == 0.0 || t == 1.0)
return t;
return t < threshold ? 0.0 : 1.0;
}
