performSemanticsAction abstract method
- SemanticsActionEvent action
Called whenever the platform requests an action to be performed on a SemanticsNode.
This callback is invoked when a user interacts with the app via an accessibility service (e.g. TalkBack and VoiceOver) and initiates an action on the focused node.
@protected void performSemanticsAction(ui.SemanticsActionEvent action);
