MockChatClient class

In-memory ChatClient for testing and prototyping without a backend.

Stores rooms, users, and messages locally. Events are emitted synchronously when messages are sent. Use emitEvent to simulate server-side events.

Methods

addMessage(String roomId, ChatMessage message) → void

cancelPendingRequests([String reason = 'cancelled']) → void

Cancels every in-flight REST request.

override

connect() → Future<void>

Opens the real-time connection (WebSocket/SSE/polling) honoring ChatConfig.realtimeMode.

override

disconnect() → Future<void>

Closes the real-time connection without clearing state.

override

dispose() → Future<void>

Releases all resources. The client must not be used after this call.

override

emitEvent(ChatEvent event) → void

logout() → Future<void>

Disconnects and clears all local state (rooms, messages, contacts).

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyTokenRotated() → Future<void>

Notifies the server (via WebSocket) that the auth token has been rotated.

override

refresh() → Future<void>

Force a refresh of the room list and (in polling/manual modes) pull new messages for any room that changed.

override

refreshRoom(String roomId) → Future<void>

Like refresh but scoped to a single room.

override

seedRoom(ChatRoom room) → void

Test helper: register a room directly in the mock store so subsequent client.rooms.get(roomId) calls return a proper RoomDetail.

seedRoomMeta(String roomId, {int? unread, bool? pinned, bool? muted}) → void

Test/demo helper: seed chat-list metadata (unread badge, pinned, muted) that the real backend computes/stores but the mock ChatRoom model doesn't carry. Null args leave the current value untouched.

seedUser(ChatUser user) → void

Test helper: register a user directly in the mock store so subsequent client.users.get(userId) calls return them. Pair with seedRoom when a test exercises the DM-draft hydration path.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
