        finalResults.add(e);
      }
    });
  });
  var len = -1;
  while (len != finalResults.length) {
    results = finalResults.toList();
    len = finalResults.length;
    results.forEach((r) {
      value.execute([r], passed).forEach((e) {
        if (notFoundInList(finalResults, e)) {
          finalResults.add(e);
