Implementation

Future<int> count([String query = '']) async {
  String url = (query.isEmpty)
      ? "$dataEndpointUri/count"
      : "$dataEndpointUri/count?query=$query";

  http.Response response = await httpr.get(url, headers: headers);
  int httpStatusCode = response.statusCode;

  if (httpStatusCode == HttpStatus.ok) {
    return int.tryParse(response.body) ?? 0;
  }
  // All other cases are treated as an error.
  Map<String, dynamic> responseJson =
      json.decode(response.body) as Map<String, dynamic>;
  throw CarpServiceException.fromMap(httpStatusCode, responseJson);
}
