QuickRTCConsumer class

A comprehensive wrapper widget that combines Provider, Listener, and Builder.

QuickRTCConsumer is the recommended way to wrap your entire conference UI. It provides:

  • Provider: Makes controller accessible to all descendants via context
  • Listener: Handles side effects (errors, navigation, snackbars)
  • Builder: Rebuilds UI reactively when state changes

The builder receives BOTH state AND controller, giving you full access to read state and invoke actions.

Basic Usage

QuickRTCConsumer(
  controller: _controller,
  builder: (context, state, controller) {
    return VideoGrid(
      participants: state.participantList,
      onLeave: () => controller.leaveMeeting(),
    );
  },
)

With Error Handling

QuickRTCConsumer(
  controller: _controller,
  listenWhen: (prev, curr) => prev.error != curr.error,
  listener: (context, controller) {
    if (controller.state.hasError) {
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(content: Text(controller.state.error!)),
      );
    }
  },
  buildWhen: (prev, curr) => prev.participantCount != curr.participantCount,
  builder: (context, state, controller) {
    return ConferenceView(state: state);
  },
  onError: (context, error) => ErrorScreen(message: error),
)

Accessing Controller in Descendants

Inside the builder's widget tree, you can access the controller:

// For actions (doesn't subscribe to changes)
final controller = QuickRTCProvider.read(context);
await controller.leaveMeeting();

// For state (subscribes to changes - use in build methods)
final state = QuickRTCProvider.stateOf(context);
