Implementation

List<Poll> generateRandomPolls(GenerateRandomPollsOptions options) {
  final List<String> pollTypes = ['trueFalse', 'yesNo', 'custom'];
  final List<Poll> polls = [];

  for (int i = 0; i < options.numberOfPolls; i++) {
    final String type = pollTypes[Random().nextInt(pollTypes.length)];
    List<String> options;

    switch (type) {
      case 'trueFalse':
        options = ['True', 'False'];
        break;
      case 'yesNo':
        options = ['Yes', 'No'];
        break;
      case 'custom':
        options = List<String>.generate(
          Random().nextInt(5) + 2,
          (idx) => 'Option ${idx + 1}',
        );
        break;
      default:
        options = [];
    }

    final poll = Poll(
      id: '${i + 1}', // String ID for consistency
      question: 'Random Question ${i + 1}',
      type: type,
      options: options,
      votes: List<int>.filled(options.length, 0),
      status: 'inactive', // or 'active'
      voters: {},
    );

    polls.add(poll);
  }

  return polls;
