CometChat Calls SDK v5 — Audio Controls (Flutter)

Overview

Control audio during an active call session — mute/unmute microphone and switch audio output device.

Key Imports

import 'package:cometchat_calls_sdk/cometchat_calls_sdk.dart';

Implementation

Mute/Unmute Audio

final session = CallSession.getInstance();

// Mute
await session?.muteAudio();

// Unmute
await session?.unMuteAudio();

// Toggle
await session?.toggleMuteAudio();

// Check state
bool isMuted = session?.isAudioMuted ?? false;

Switch Audio Mode

final session = CallSession.getInstance();

// Switch to speaker
await session?.setAudioModeType(AudioMode.speaker);

// Switch to earpiece
await session?.setAudioModeType(AudioMode.earpiece);

// Switch to bluetooth
await session?.setAudioModeType(AudioMode.bluetooth);

// Switch to headphones
await session?.setAudioModeType(AudioMode.headphones);

Listen for Audio Events

class MyMediaListener implements MediaEventListeners {
  @override
  void onAudioMuted() {
    debugPrint("Audio muted");
  }

  @override
  void onAudioUnMuted() {
    debugPrint("Audio unmuted");
  }

  @override
  void onAudioModeChanged(AudioMode audioMode) {
    debugPrint("Audio mode changed to: ${audioMode.value}");
  }
}

• Audio controls only work during an active session
• isAudioMuted reflects the local mute state
• Audio mode changes may not be available on all devices
