semanticsTooltip property
final
The text to display in the tooltip's semantics announcement.
This string is used by assistive technologies, most notably screen readers like TalkBack and VoiceOver, to describe the tooltip's purpose.
Providing a non-empty string adds a Semantics tooltip string for assistive technologies. If the tooltip should not have a semantic description, this property must be explicitly set to null.
Implementation
final String? semanticsTooltip;
