parseCallQuality method

CallQualityInfo parseCallQuality(Map data)

Parse call quality data from native event

Example usage:

final tracker = CallQualityTracker();

OmicallClient.instance.setCallQualityListener((data) {
  final info = tracker.parseCallQuality(data);

  // Handle loading indicator
  if (info.shouldShowLoading) {
    EasyLoading.show();
  } else {
    EasyLoading.dismiss();
  }

  // Display MOS score
  setState(() {
    callQuality = info.mosDisplay;
  });
});

Implementation

CallQualityInfo parseCallQuality(Map<dynamic, dynamic> data) {
  final quality = data["quality"] as int? ?? 0;
  final stat = data["stat"] as Map<dynamic, dynamic>? ?? {};

  final currentLcnValue = stat["lcn"] as int? ?? 0;
  final mos = (stat["mos"] as num?)?.toDouble() ?? 0.0;
  final jitter = (stat["jitter"] as num?)?.toDouble() ?? 0.0;
  final latency = (stat["latency"] as num?)?.toDouble() ?? 0.0;
  final packetLoss = (stat["ppl"] as num?)?.toDouble() ?? 0.0;
  final requestCount = stat["req"] as int? ?? 0;

  bool shouldShowLoading = false;
  bool isNetworkRecovered = false;

  // Track consecutive same LCN values
  if (currentLcnValue == _lastLcnValue && currentLcnValue != 0) {
    _consecutiveSameLcnCount++;

    // Show loading overlay after threshold consecutive same values (indicating poor network)
    if (_consecutiveSameLcnCount >= loadingThreshold) {
      shouldShowLoading = true;
    }
  } else {
    // LCN value changed or is 0 - network is working
    if (_consecutiveSameLcnCount > 0) {
      isNetworkRecovered = true;
    }
    _consecutiveSameLcnCount = 0;
    shouldShowLoading = false;
  }

  _lastLcnValue = currentLcnValue;

  return CallQualityInfo(
    mos: mos,
    lcn: currentLcnValue,
    quality: quality,
