 The navigator will remember the last unhandled action (such as an unhandled deep link) if `routeNamesChangeBehavior: 'lastUnhandled'` is specified. When the list of route names changes (e.g. new screens become available), it will try to handle the action again. See [`routeNamesChangeBehavior` docs](/docs/8.x/navigator#route-names-change-behavior) for more details.
