RxList in Getx bindStream, but Obx keep get old data emmited

[OpenJarvisAI]

my project is a little comlicated, but I have a type binded a Stream from sql.

Each time I entered a new chat page from history, it can happens get old room messages, it's weired.

I think it caused by bindStream,

void getMessagesWithContactOrRoomMem(String roomId, bool isGroup,
{int perPage = 25, int pageNum = 0}) {
if (isGroup) {
var msgs = MyDatabase.instance()!
.messageDao
.getMessagesWithRoomMemberByRoomId(roomId,
perPage: perPage, pageNum: pageNum);
// out.stream = msgs;

  roomMsgs.bindStream(msgs);
  // return msgs;
} else {
  var msgs = MyDatabase.instance()!
      .messageDao
      .getMessagesWithContactByRoomId(roomId,
          perPage: perPage, pageNum: pageNum);
  roomMsgs.bindStream(msgs);
  // return msgs;
}

}

Help me
