render method
Should render this Particle to given Canvas.
Default behavior is empty, so that it's not required to override this in a Particle that renders nothing and serve as a behavior container.
Implementation
@override
void render(Canvas canvas) {
canvas.save();
final current = _tmpVector
..setFrom(from)
..lerp(to, progress);
canvas.translateVector(current);
super.render(canvas);
canvas.restore();
}
