When there is too much conversation messages, calling conversationManager.getConversationListSplit will report an error.

Use open-im-flutter-demo

1. Create 1,000 group conversation messages.
2. After synchronization.
3. Kill the app process and re-enter.
4. Go to conversation.
5. Scroll to the bottom.
6. Scroll again.
7. When offset is 320.
8. Error occurred.

Additional context

[std-s]

Hi, set count to a smaller value. For example, 50, 100.

[fatesinger]

Now the count is 40. I changed the count to 20, but the problem still remains.

final pageSize = 20;

void onLoading() async {
  late List<ConversationInfo> list;
  try {
    list = await _request(this.list.length);
    this.list.addAll(list);
  } finally {
    if (list.isEmpty || list.length < pageSize) {
      refreshController.loadNoData();
    } else {
      refreshController.loadComplete();
    }
  }
}

_request(int offset) =>
    OpenIM.iMManager.conversationManager.getConversationListSplit(
      offset: offset,
      count: pageSize,
    );

[std-s]

The function reporting the error is "getFriendList".

[fatesinger]

Please try this code.

List list = [];
final pageSize = 50;

getConversationList(int offset) async {
  var list = await OpenIM.iMManager.conversationManager.getConversationListSplit(
    offset: offset,
    count: pageSize,
  );
  return list;
}

FloatingActionButton(
  onPressed: () async {
    var result = await getConversationList(400);
    setState(() {
      list = result;
    });
  },
)
