getNodeBounds method
Gets the bounding rectangle for a specific node.
Returns null if the node doesn't exist.
Example:
final bounds = controller.getNodeBounds('node1');
if (bounds != null) {
print('Node size: ${bounds.width} x ${bounds.height}');
}
Implementation
Rect? getNodeBounds(String nodeId) {
final node = _nodes[nodeId];
if (node == null) return null;
return node.getBounds();
}
