renderTransform property
This node's render transform. Equivalent to localTransform, except
that it's stored in a Canvas-friendly typed_data structure for
performance reasons.
The returned float list is owned by this node and should not be retained.
Implementation
@visibleForTesting
Float64List get renderTransform {
final transform = _lastRenderTransform;
final cosA = math.cos(angle);
final sinA = math.sin(angle);

..[0] = cosA * scale.x
..[1] = sinA * scale.x
..[4] = -sinA * scale.y
..[5] = cosA * scale.y
..[12] = position.x
..[13] = position.y;
return transform;
