void SendLayoutChanged(AccessibilityNode nodeToFocus = null)
Parameters
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.
Remarks
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.
