mergeSemantics method

Widget mergeSemantics({
  1. Key? key,
})

Merges the semantics of its descendants.

Causes all the semantics of the subtree rooted at this node to be merged into one node in the semantics tree. For example, if you have a widget with a Text node next to a checkbox widget, this could be used to merge the label from the Text node with the "checked" semantic state of the checkbox into a single node that had both the label and the checked state. Otherwise, the label would be presented as a separate feature than the checkbox, and the user would not be able to be sure that they were related.

Implementation

Widget mergeSemantics({Key? key}) {
  return MergeSemantics(
    key: key,
    child: this,
  );
}
