API রেফারেন্স

Main widget

The drop-in LiveKit live-streaming room widget.

UTDLiveRoomwidget
const UTDLiveRoom({required String appId, required String appKey, required String userId, required String userName, required String roomId, required String roomOwnerId, Set<String> adminIds, ..., UTDLiveRoomConfig config, void Function(UTDRoomController)? onControllerReady, ...})

A LiveKit-based video live room. The host's camera fills the screen as the background; up to maxGuestTiles invited guests appear as floating video tiles. Audience watch + chat and may request to go live.

প্যারামিটার

  • appIdStringআবশ্যক

    App ID for the UTD Stream Engine (X-App-Id).

  • appKeyStringআবশ্যক

    Publishable app key (no backend). The kit mints tokens directly with X-App-Key; the server secret never ships.

  • userIdStringআবশ্যক

    Local user's identity.

  • userNameStringআবশ্যক

    Local user's display name.

  • roomIdStringআবশ্যক

    Room / LiveKit room name to join.

  • adminIdsSet<String>ডিফল্ট = const {}

    Identities the owner will promote to admin (moderators) once present in the room.

  • adminIdsResolverFuture<Set<String>> Function()?ডিফল্ট = null

    Async source for adminIds resolved after join; the owner self-promotes them via the role endpoint.

  • adminIdsNowSet<String> Function()?ডিফল্ট = null

    Optional sync probe for the admin list at token time (no waiting).

    Called when the connection succeeds (true) or fails (false).

  • onConnectErrorvoid Function(Object, StackTrace)?ডিফল্ট = null

    Called on connect failure; if null the kit shows its built-in connect-error view.

  • controllerUTDRoomController?ডিফল্ট = null

    Reuse an existing already-connected controller, e.g. restoring from a minimized overlay.

Room controller

Imperative facade over the room: connection lifecycle, participants, roles, stage, moderation, and sub-controllers.
