contentReplacements property

Map<SemanticNodeId, SemanticNode>? get contentReplacements

The nodes the most recently applied frame rebuilt, when it changed only the content of nodes already in the tree: those nodes and their ancestors, by id. A consumer can advance a SemanticsOwner with updateRetainedNodes instead of diffing the whole tree. Null after a full frame or a structural patch.

Implementation

Map<SemanticNodeId, SemanticNode>? get contentReplacements =>
    _contentReplacements;
