inputsFromType method

List<Map<String, String>> inputsFromType(String inputTypeId)

Get a list of inputs from input type. Returns an array of maps with keys id and name.

Implementation

  final List<Map<String, String>> list = [];

  final sourceProps = _lib.obs_get_source_properties(inputTypeId.int8());

    var property = _lib.obs_properties_first(sourceProps);
    while (property != ffi.nullptr) {
      final type = _lib.obs_property_get_type(property);
      if (type == obs_property_type.OBS_PROPERTY_LIST) {

          final uid = _lib.obs_property_list_item_string(property, index).string;
          if (disabled == 0 && name != null && uid != null && name.isNotEmpty && uid.isNotEmpty) {
            list.add({"id": uid, "name": name, "type_id": inputTypeId});
          }
        }
      }
      propertyOut.value = property;
      final rv = _lib.obs_property_next(propertyOut);
