Implementation

@override
Future<List<ParticipantData>> getParticipantDataList(
    List<String> studyDeploymentIds) async {
  // early out if empty list
  if (studyDeploymentIds.isEmpty) return [];

  Map<String, dynamic> responseJson =
      await _rpc(GetParticipantDataList(studyDeploymentIds));

  // we expect a list of 'items'
  List<dynamic> items = responseJson['items'] as List<dynamic>;
  if (items.isEmpty) return [];

  List<ParticipantData> data = [];
  for (var item in items) {
    data.add(ParticipantData.fromJson(item as Map<String, dynamic>));
  }

  return data;
