Toast
also known as toast notification, toast message
A toast is a small, transient notification that appears briefly (a few seconds) to give lightweight feedback, then disappears automatically without needing user action. It's non-blocking and non-interactive. On Android, 'Toast' is specifically a system message with no buttons and no swipe-to-dismiss.
