Implementation

static Future<void> logout(
    {required Function(String message)? onSuccess,
    required Function(CometChatException excep)? onError}) async {
  try {
    // Get SDK instance
    final sdk = SdkRegistry.getInstance();

    // Cancel stream subscriptions before logout
    _cancelStreamSubscriptions();

    // Call native Dart auth repository
    await sdk.auth.logout();

    // Notify login listeners
    _loginListeners.values.forEach((element) {
      element.logoutSuccess();
    });

    // Call success callback
    if (onSuccess != null) onSuccess('Logout successful');
  } on SdkException catch (sdkEx) {
    // Convert SdkException to CometChatException
    final cometChatEx = CometChatException(
      sdkEx.code,
      sdkEx.details ?? sdkEx.message,
      sdkEx.message,
    );

    // Notify login listeners
    _loginListeners.values.forEach((element) {
