Supported events
Example usage
announceForAccessibility
Trigger an accessibility announcement for the screen reader. It programmatically announces the specified message to notify users of important changes in the app’s UI, such as status updates or alerts. The announcement isn’t associated with a specific UI element and is best for general notifications.Example usage
announceForAccessibilityWithOptions
TheannounceForAccessibilityWithOptions method extends the functionality of announceForAccessibility by allowing developers to customize the behavior of announcements such as waiting for existing announcements to complete before announcing a new message.
Example usage
Accepted values

true in the options object.
isScreenReaderEnabled
Use theisScreenReaderEnabled method to query whether a screen reader is currently enabled.
