updateChildren method

@override LeafNode updateChildren(covariant List<GreenNode> newChildren)

Return a copy of this node with new children.

Subclasses should override this method. This method provides a general interface to perform structural updates for the green tree (node replacement, insertion, etc).

Please ensure children works in the same order as updateChildren, computeChildOptions, and buildWidget.

Implementation

@override
LeafNode updateChildren(List<GreenNode> newChildren) {
  assert(newChildren.isEmpty);
  return this;
}
