MemoryChatLocalDatasource class

In-memory implementation of ChatLocalDatasource. Data is lost when the process exits. The ChatResult wrap returns ChatSuccess for every operation — no I/O means nothing to fail on.

override

hideMessageLocally(String roomId, String messageId) → Future<ChatResult<void>>

"Delete for me" persistence: a per-room set of message IDs the user explicitly hid via messages.deleteLocally. The network list endpoint has no concept of per-user hiding, so without this set the tombstone (or the deleted message) re-appears every time the chat is re-opened. Default implementations are no-ops so non-persistent datasources (memory) keep working, at the cost of losing the hidden set on app restart.

override

loadCacheTimestamps() → Future<Map<String, DateTime>>

override

markKicked(String roomId) → Future<ChatResult<void>>

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reconcileUnreads(List<UnreadRoom> unreads) → Future<ChatResult<void>>

Replaces the cached unread set with exactly unreads, removing any previously cached room absent from the new list. Use this for an authoritative type='all' room listing so rooms deleted or left on the server stop reappearing from cache (plain saveUnreads merges and never evicts). The default implementation diffs against getUnreads and deleteUnread; datasources with a native "replace box" primitive should override it for atomicity.

override

saveCacheTimestamps(Map<String, DateTime> timestamps) → Future<void>

override

saveContacts(List<ChatContact> contacts) → Future<ChatResult<void>>

override

saveInvitedRooms(List<InvitedRoom> invitedRooms) → Future<ChatResult<void>>

override

saveMessages(String roomId, List<ChatMessage> messages) → Future<ChatResult<void>>

override

saveOfflineQueue(List<Map<String, dynamic>> operations) → Future<ChatResult<void>>

override

savePendingMessage(String roomId, ChatMessage message, {bool isFailed = false}) → Future<ChatResult<void>>

override

savePins(String roomId, List<MessagePin> pins) → Future<ChatResult<void>>

override

saveReactions(String roomId, String messageId, List<AggregatedReaction> reactions) → Future<ChatResult<void>>

override

saveReceipts(String roomId, List<ReadReceipt> receipts) → Future<ChatResult<void>>

override

saveRoomDetail(RoomDetail detail) → Future<ChatResult<void>>

override

saveRoomMembers(String roomId, ChatPaginatedResponse<RoomUser> members) → Future<ChatResult<void>>

Room member roster, as returned by an UNPAGINATED, UNEXPANDED members.list — the only shape MembersApi caches, so one record per room can never be served to a caller that asked for a different one. hasMore and totalCount travel with the items because a hit that invented them would break the paginator of a large group.

override

saveRooms(List<ChatRoom> rooms) → Future<ChatResult<void>>

override

saveUnreads(List<UnreadRoom> unreads) → Future<ChatResult<void>>

override

saveUsers(List<ChatUser> users) → Future<ChatResult<void>>

override

setClearedAt(String roomId, DateTime timestamp) → Future<ChatResult<void>>

override

toString() → String

A string representation of this object.
