@override
Future<bool> validateToken(String token) async {
  log.info("Verifying token [redacted]....");

  var response = await networkService.post(
      "${config.kMoodleServerAdress}/webservice/rest/server.php",
      body: {
        "wstoken": token,
        "moodlewsrestformat": "json",
      });

  if (response.isNotOk) {
    log.info(
        "Got response ${response.statusCode} from token validation. Invaildating token by default.");

    return false;
  }

  final body = response.body as JSON;

  // if errorcode is 'accessexception' or 'invalidtoken' the token is invalid

  var errorCode = body["errorcode"];

  if (errorCode == "accessexception") {
    log.info("Token expired");

    return false;
  }

  if (errorCode == "invalidtoken") {
    log.info("Token invalid");

    return false;
  }

  log.info("Token is valid");

  return true;
}
