Retrieve a list of voters

Create a PollVoterListQuery instance to retrieve a list of voters matching the specifications set by PollVoterListQueryParams. After a list of voters is successfully retrieved, you can access the data of each voter from the result list through the votes parameter of the callback handler.

Dart

try {
  // Retrieve a list of voters.
  final query = await PollVoterListQuery(
    params: PollVoterListQueryParams(
      channelType: channel.channelType,
      channelUrl: channel.channelUrl,
      pollId: POLL_ID,
      pollOptionId: POLL_OPTIONS_ID,
    ),
  );
  final voters = await query.next();
} catch (e) {
  // Handle error.
}
