excludeFromSemantics property
final
Whether the tooltip's message or richMessage should be excluded from the semantics tree.
Defaults to false. A tooltip will add a Semantics label that is set to Tooltip.message if non-null, or the plain text value of Tooltip.richMessage otherwise. Set this property to true if the app is going to provide its own custom semantics label.
Implementation
final bool? excludeFromSemantics;
