Implementation
Offset get offset {
assert(
context != null,
"Tried to get the offset of a focus node that didn't have its context set yet.\n"
'The context needs to be set before trying to evaluate traversal policies. This '
'is typically done with the attach method.');
final RenderObject object = context.findRenderObject();
return MatrixUtils.transformPoint(object.getTransformTo(null), object.semanticBounds.topLeft);
}
