updateChildren method

@override StretchyOpNode updateChildren(covariant List<EquationRowNode> 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
StretchyOpNode updateChildren(List<EquationRowNode> newChildren) =>
    StretchyOpNode(
      above: newChildren[0],
      below: newChildren[1],
      symbol: symbol,
    );
