Implementation

Future<ChatCursorResult<ChatMessageReaction>> fetchReactionDetail({
  required String messageId,
  required String reaction,
  String? cursor,
  int pageSize = 20,
}) async {
  try {
    Map req = {
      "msgId": messageId,
      "reaction": reaction,
    };
    req.putIfNotNull("cursor", cursor);
    req.putIfNotNull("pageSize", pageSize);
    Map result = await platform_interface.Client.instance.chatManager.callNativeMethod(
      ChatMethodKeys.fetchReactionDetail,
      req,
    );
    ChatError.hasErrorFromResult(result);
    final data = result[ChatMethodKeys.fetchReactionDetail];
    if (data != null) {
      return ChatCursorResult<ChatMessageReaction>.fromJson(data,
          dataItemCallback: (value) {
        return ChatMessageReaction.fromJson(value);
      });
    } else {
      return ChatCursorResult<ChatMessageReaction>(null, []);
    }
  } catch (e) {
    rethrow;
  }
}
