StreamChatClient class

The official Dart client for Stream Chat, a service for building chat applications. This library can be used on any Dart project and on both mobile and web apps with Flutter.

You can sign up for a Stream account at https://getstream.io/chat/

The Chat client will manage API call, event handling and manage the websocket connection to Stream Chat servers.

final client = StreamChatClient("stream-chat-api-key");

Constructors

StreamChatClient(String apiKey, {Level logLevel = Level.WARNING, LogHandlerFunction logHandlerFunction = StreamChatClient.defaultLogHandler, RetryPolicy? retryPolicy, String? baseURL, String? baseWsUrl, Duration connectTimeout = kDefaultConnectTimeout, Duration receiveTimeout = kDefaultReceiveTimeout, StreamChatApi? chatApi, WebSocket? ws, AttachmentFileUploaderProvider attachmentFileUploaderProvider = StreamAttachmentFileUploader.new, Iterable<Interceptor>? chatApiInterceptors, HttpClientAdapter? httpClientAdapter, bool recoverStateOnReconnect = true, bool isLocalUnreadCountEnabled = false}): Create a client instance with default options. You should only create the client once and re-use it across your application.

Properties

appSettings → AppSettings: The cached AppSettings for this client.
no setter
channelDeliveryReporter → ChannelDeliveryReporter: Manages delivery receipt reporting for channel messages.
latefinal
chatPersistenceClient ↔ ChatPersistenceClient?: Chat persistence client
getter/setter pair
eventStream → Stream<Event>: Stream of Event coming from _ws connection Listen to this or use the on method to filter specific event types
no setter
hashCode → int: The hash code for this object.
no setterinherited
isLocalUnreadCountEnabled → bool: Whether the SDK should track unread counts locally, on-device, for channels that have read events disabled (e.g. livestream channel types).
final
logger → Logger: Client specific logger instance. Refer to the class Logger to learn more about the specific implementation.
latefinal
logHandlerFunction → LogHandlerFunction: A function that has a parameter of type LogRecord. This is called on every new log record. By default the client will use the handler returned by _getDefaultLogHandler. Setting it you can handle the log messages directly instead of have them written to stdout, this is very convenient if you use an error tracking tool or if you want to centralize your logs into one facility.
final
logLevel → Level: By default the Chat client will write all messages with level Warn or Error to stdout.
final
persistenceEnabled → bool: Returns True if the chatPersistenceClient is available and connected. Otherwise, returns False.
no setter
recoverStateOnReconnect ← bool: Whether the client should automatically refresh local state from the server when the WebSocket connection recovers.
no getter
retryPolicy → RetryPolicy: The retry policy options getter
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
state ↔ ClientState: This client state
getter/setter pair
wsConnectionStatus → ConnectionStatus: The current status value of the _ws connection
no setter
wsConnectionStatusStream → Stream<ConnectionStatus>: This notifies the connection status of the _ws connection. Listen to this to get notified when the _ws tries to reconnect.
no setter
