getLastTransform method Null safety
The transform that was used during the last composition phase.
If the link was not linked to a LeaderLayer, or if this layer has a degenerate matrix applied, then this will be null.
This method returns a new Matrix4 instance each time it is invoked.
Implementation
Matrix4? getLastTransform() {
if (_lastTransform == null) {
return null;
}
final Matrix4 result = Matrix4.translationValues(-_lastOffset!.dx, -_lastOffset!.dy, 0.0);
result.multiply(_lastTransform!);
return result;
}
