Sets this room as a direct chat for this user if not already.
ban(String userID) → Future<void>
Call the SDN API to ban a user from this room.
calcEncryptionHealthState() → Future<EncryptionHealthState>
Calculates how secure the communication is. When all devices are blocked or verified, then this returns EncryptionHealthState.allVerified. When at least one device is not verified, then it returns EncryptionHealthState.unverifiedDevices. Apps should display this health state next to the input text field to inform the user about the current encryption security level.
canChangeStateEvent(String action) → bool
returns if user can change a particular state event by comparing ownPowerLevel with possible overrides in events, if not present compares ownPowerLevel with state_default
canSendEvent(String eventType) → bool
The level required to send a certain event. Defaults to 0 if there is no events_default set or there is no power level state in the room.
canSendNotification(String userid, {String notificationType = 'room'}) → bool
The power level requirements for specific notification types.
enableEncryption({int algorithmIndex = 0}) → Future<void>
enableGroupCalls() → Future<void>
sets the org.sdn.msc3401.call.member power level to users default for group calls, needs permissions to change power levels
forget() → Future<void>
Call the SDN API to forget this room if you already left it.
getDefaultPowerLevel(Map<String, dynamic> powerLevelMap) → int
Takes in [m.room.power_levels].content and returns the default power level
getEventById(String eventID) → Future<Event?>
Searches for the event in the local cache and then on the server if not found. Returns null if not found anywhere.
getEventContext(String eventId) → Future<TimelineChunk?>
getLocalizedDisplayname([SDNLocalizations i18n = const SDNDefaultLocalizations()]) → String
Returns a localized displayname for this server. If the room is a groupchat without a name, then it will return the localized version of 'Group with Alice' instead of just 'Alice' to make it different to a direct chat. Empty chats will become the localized version of 'Empty Chat'. This method requires a localization class which implements SDNLocalizations
getMention(String mention) → String?
returns the resolved mxid for a mention string, or null if none found
getParticipants([List<Membership> membershipFilter = const [Membership.join, Membership.invite, Membership.knock]]) → List<User>
Returns all participants for this room. With lazy loading this list may not be complete. Use requestParticipants in this case. List membershipFilter defines with what membership do you want the participants, default set to [Membership.join, Membership.invite, Membership.knock]
getPowerLevelByUserId(String userId) → int
Returns the power level of the given user ID. If a user_id is in the users list, then that user_id has the associated power level. Otherwise they have the default level users_default. If users_default is not supplied, it is assumed to be 0. If the room contains no m.room.power_levels event, the room’s creator has a power level of 100, and all other users have a power level of 0.
getState(String typeKey, [String stateKey = '']) → Event?
Returns the Event for the given typeKey and optional stateKey. If no stateKey is provided, it defaults to an empty string.
getTimeline({void onChange(int index)?, void onRemove(int index)?, void onInsert(int insertID)?, void onNewEvent()?, void onUpdate()?, String? eventContextId}) → Future<Timeline>
Creates a timeline from the store. Returns a Timeline object. If you just want to update the whole timeline on every change, use the onUpdate callback. For updating only the parts that have changed, use the onChange, onRemove, onInsert and the onHistoryReceived callbacks. This method can also retrieve the timeline at a specific point by setting the eventContextId
getUserByMXIDSync(String mxID) → User
getUserDeviceKeys() → Future<List<DeviceKeys>>
Returns all known device keys for all participants in this room.
invite(String userID) → Future<void>
Call the SDN API to invite a user to this room.
join({bool leaveIfNotFound = true}) → Future<void>
Call the SDN API to join this room if the user is not already a member. If this room is intended to be a direct chat, the direct chat flag will automatically be set.
kick(String userID) → Future<void>

leave() → Future<void>
Call the SDN API to leave this room. If this room is set as a direct chat, this will be removed too.
markUnread(bool unread) → Future<void>
Sets an unread flag manually for this room. This changes the local account data model before syncing it to make sure this works if there is no connection to the node. This does not set a read marker!
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
postLoad() → Future<void>
Post-loads the room. This load all the missing state events for the room from the database If the room has already been loaded, this does nothing.
postReceipt(String eventId, {ReceiptType type = ReceiptType.mRead}) → Future<void>
This API updates the marker for the given receipt type to the event ID specified. In general you want to use setReadMarker instead to set private and public receipt as well as the marker at the same time.
powerForChangingStateEvent(String action) → int
returns the powerlevel required for chaning the action defaults to state_default if action isn't specified in events override. If there is no state_default in the m.room.power_levels event, the state_default is 50. If the room contains no m.room.power_levels event, the state_default is 0.
redactEvent(String eventId, {String? reason, String? txid}) → Future<String?>
Redacts this event. Throws ErrorResponse on error.
removeFromDirectChat() → Future<void>

requestHistory({int historyCount = defaultHistoryCount, void onHistoryReceived()?, dynamic direction = Direction.b}) → Future<int>
Request more previous events from the server. historyCount defines how much events should be received maximum. When the request is answered, onHistoryReceived will be triggered before the historical events will be published in the onEvent stream. Returns the actual count of received timeline events.
requestParticipants([List<Membership> membershipFilter = const [Membership.join, Membership.invite, Membership.knock], bool suppressWarning = false]) → Future<List<User>>
Request the full list of participants from the server. The local list from the store is not complete if the client uses lazy loading. List membershipFilter defines with what membership do you want the participants, default set to [Membership.join, Membership.invite, Membership.knock]
requestSessionKey(String sessionId, String senderKey) → Future<void>
requestUser(String mxID, {bool ignoreErrors = false, bool requestProfile = true}) → Future<User?>

sendLocation(String body, String geoUri, {String? txid}) → Future<String?>
Sends the location with description body and geo URI geoUri into a room. Returns the event ID generated by the server for this message.
sendReaction(String eventId, String key, {String? txid}) → Future<String?>
Sends a reaction to an event with an eventId and the content key into a room. Returns the event ID generated by the server for this reaction.
sendTextEvent(String message, {String? txid, Event? inReplyTo, String? editEventId, bool parseMarkdown = true, bool parseCommands = true, String msgtype = MessageTypes.Text, String? threadRootEventId, String? threadLastEventId}) → Future<String?>
Sends a normal text message to this room. Returns the event ID generated by the server for this message.
setAvatar(SDNFile? file) → Future<String>
Uploads a new user avatar for this room. Returns the event ID of the new m.room.avatar event. Leave empty to remove the current avatar.

setReadMarker(String? eventId, {String? mRead, bool? public}) → Future<void>
Sets the position of the read marker for a given room, and optionally the read receipt's location. If you set public to false, only a private receipt will be sent. A private receipt is always sent if mRead is set. If no value is provided, the default from the client is used. You can leave out the eventId, which will not update the read marker but just send receipts, but there are few cases where that makes sense.
setSpaceChild(String roomId, {List<String>? via, String? order, bool? suggested}) → Future<void>
