lerp method
Returns the value this variable has at the given animation clock value.
The default implementation of this method uses the +
, -
, and *
operators on T
. The begin and end properties must therefore be
non-null by the time this method is called.
In general, however, it is possible for this to return null, especially
when t
=0.0 and begin is null, or t
=1.0 and end is null.
Implementation
Color? lerp(double t) {
if (t < 0.5) return Color.lerp(begin, middle, t * 2);
return Color.lerp(middle, end, (t - 0.5) * 2);
}
