[Bug] When tagging in a group chat, not all members are displayed

[tprudentova]

2.6.10, 2.6.11, tested on Chrome, Safari, Android, linagora.com

1. Open a group chat. The bug can be reproduced easier in chats that have lots of members
2. Type @ in the composer
3. Not all of the members are displayed in the drop-down list (in the video there are 11 members in a chat, only 7 members in a tag list)
   NB: If you go to group info and click "Load more" in the list of members, they will be displayed in tags alright

How to cache Participants for each room (Hive) ???

• when a user will be added to local db?

• when a user will be added to local db?

1. imports a dumped session

  for (final key in json[_roomMembersBoxName]!.keys) {
        await _roomMembersBox.put(key, json[_roomMembersBoxName]![key]);
      }

2. When using store event

storeEventUpdate()

...


if (eventUpdate.content['type'] == EventTypes.RoomMember) {
        await _roomMembersBox.put(
            TupleKey(
              eventUpdate.roomID,
              eventUpdate.content['state_key'],
            ).toString(),
            eventUpdate.content);
      }

Some method using store event

decryptRoomEvent()

setInboundGroupSession()

getEventByPushNotification()

_handleRoomEvents()

requestUser()
