| Parameter | Description |

| nodeToFocus | An optional node to be focused by the screen reader after processing the notification. If a node is not provided and the currently focused node still exists, the screen reader does not change its focus. |
Notifies the screen reader that the layout of the screen changed and optionally requests it to move its focus to a given accessibility node.
Call this method to notify the screen reader of minor adjustments to the user interface (for example,
when a dropdown is opened or closed), or to update the screen reader focus as a result of such changes
(for example, to move it off an accessibility node that may have been removed or deactivated so that the
screen reader's focus indicator isn’t stuck on a stale node).
Calling this method prompts the screen reader to invalidate its cache of the accessibility hierarchy.
Note: On Windows and macOS, duplicate calls with the same argument are ignored by the screen reader.
