Implementation

      ),
    );
  }

  final callback = callbackUrlScheme ?? await _loopbackUrl();
  final exchange = url.path.contains(_sessionOAuth2Path);
  final result = await _authenticate(
    url.replace(
      path: exchange
          ? url.path.replaceFirst(_sessionOAuth2Path, _tokenOAuth2Path)
          : url.path,
      queryParameters: {
        ...url.queryParametersAll,
        'success': [callback],
        'failure': [callback],
      },
    ),
    callback,
  );
  if (!exchange) {
    return _saveSession(result);
  }

  final userId = result.queryParameters['userId'];

  }
  await call(
    HttpMethod.post,
    path: _tokenSessionPath,
    params: {'userId': userId, 'secret': secret},
