Implementation

static Map<String, dynamic> extractData(Map<String, dynamic> dataMap) {
  Map<String, dynamic> data;

  if (dataMap[ApiFields.data] != null && dataMap[ApiFields.id] == null) {
    try {
      data = Map<String, dynamic>.from(dataMap[ApiFields.data]);
    } catch (_) {
      List<Map<String, dynamic>> resourceList =
          List<Map<String, dynamic>>.from(dataMap[ApiFields.data]);

      try {
        data = resourceList.first;
      } catch (__) {
        data = {};
      }
    }
  } else {
    data = dataMap;
  }

  return data;
