isUnregisteredToken property

bool get isUnregisteredToken

True when the service says this device token is no longer valid, so the application should stop sending to it and prune its record.

Implementation

bool get isUnregisteredToken {
  if (statusCode == 404) return true;
  final body = responseBody;
  if (body == null) return false;
  return body.contains('UNREGISTERED') || body.contains('NOT_FOUND');
}
