onDidGainAccessibilityFocus property

VoidCallback? get onDidGainAccessibilityFocus

Called when the node gains accessibility focus (the screen-reader cursor lands on it). A natural place to draw an in-scene focus indicator (a Node.highlightColor outline) or steer the camera.

Implementation

VoidCallback? get onDidGainAccessibilityFocus => _onDidGainAccessibilityFocus;

set onDidGainAccessibilityFocus (VoidCallback? value)

Implementation

set onDidGainAccessibilityFocus(VoidCallback? value) {
  _assertConvenience();
  if (value == _onDidGainAccessibilityFocus) return;
  _onDidGainAccessibilityFocus = value;
  _bump();
}
