extractCallIdFromCandidate static method

String? extractCallIdFromCandidate(Map<String, dynamic> params)

Extracts call ID from the candidate message parameters. Supports both new server format (callID in params) and legacy format (callId in dialogParams).

params The JSON object containing candidate parameters Returns the extracted UUID if found, null otherwise

Implementation

static String? extractCallIdFromCandidate(Map<String, dynamic> params) {
  String? callId;

  // Try to get call ID from multiple possible locations

  // 1. Check directly in params for "callID" (new server format)
  if (params.containsKey('callID')) {
    try {
      callId = params['callID'] as String?;
      if (callId != null) {
        GlobalLogger().i('Found callID directly in params: $callId');
      }
    } catch (e) {
      GlobalLogger().e('Failed to parse callID from params: ${e.toString()}');
    }
  }

  // 2. Fallback to dialogParams for "callId" (legacy format) if not found yet
  if (callId == null && params.containsKey('dialogParams')) {
    final dialogParams = params['dialogParams'] as Map<String, dynamic>?;
    if (dialogParams != null && dialogParams.containsKey('callId')) {
      try {
        callId = dialogParams['callId'] as String?;
        if (callId != null) {
          GlobalLogger().i('Found callId in dialogParams: $callId');
        }
      } catch (e) {
        GlobalLogger().e('Failed to parse callId from dialogParams: ${e.toString()}');
      }
    }
  }

  return callId;
