updateChildren abstract method

GreenNode updateChildren(
  1. 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

GreenNode updateChildren(covariant List<GreenNode?> newChildren);
