Implementation

Future<Map<String, List<EMMessageReaction>>> fetchReactionList({
  required List<String> messageIds,
  required ChatType chatType,
  String? groupId,
}) async {
  Map req = {
    "msgIds": messageIds,
    "chatType": chatTypeToInt(chatType),
  };
  req.putIfNotNull("groupId", groupId);
  Map result = await ChatChannel.invokeMethod(
    ChatMethodKeys.fetchReactionList,
    req,
  );

  try {
    EMError.hasErrorFromResult(result);
    Map<String, List<EMMessageReaction>> ret = {};
    for (var info in result[ChatMethodKeys.fetchReactionList].entries) {
      List<EMMessageReaction> reactions = [];
      for (var item in info.value) {
        reactions.add(EMMessageReaction.fromJson(item));
      }
      ret[info.key] = reactions;
    }
    return ret;
  } on EMError catch (e) {
    throw e;
  }
}
