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
@override
KeyframeValue lerp(double t) {
if (t <= 0) {
return begin!;
}
if (t >= 1) {
return end!;
}
return KeyframeValue.evaluate(
properties,
t,
);
}
