assembleSemanticsNode method

void assembleSemanticsNode(
  1. SemanticsNode node,
  2. SemanticsConfiguration config,
  3. Iterable<SemanticsNode> children

Assemble the SemanticsNode for this RenderObject.

If describeSemanticsConfiguration sets SemanticsConfiguration.isSemanticBoundary to true, this method is called with the node created for this RenderObject, the config to be applied to that node and the children SemanticsNodes that descendants of this RenderObject have generated.

By default, the method will annotate node with config and add the children to it.

Subclasses can override this method to add additional SemanticsNodes to the tree. If new SemanticsNodes are instantiated in this method they must be disposed in clearSemantics.


void assembleSemanticsNode(
  SemanticsNode node,
  SemanticsConfiguration config,
  Iterable<SemanticsNode> children,
) {
  assert(node == _semantics);
  // TODO(a14n): remove the following cast by updating type of parameter in either updateWith or assembleSemanticsNode
  node.updateWith(config: config, childrenInInversePaintOrder: children as List<SemanticsNode>);
