SDNN

The SDNN value is sent as part of the final results.

The application can receive the SDNN result by implementing VitalSignsListener:

Dart

@override
void onFinalResults(VitalSignsResults results) {
    VitalSign? vitalSign = results.getResult(VitalSignTypes.sdnn);
    if (vitalSign != null && vitalSign is VitalSignSdnn) {
        VitalSignSdnn sdnn = vitalSign;
        print("SDNN: ${sdnn.value}");

        print("Confidence Level: ${sdnn.confidence?.level.toString() ?? "N/A"}");
    }
}

For general information about vital signs see the Vital Signs and Health Indicators Information Page.

For a list of supported vital signs per platform and measurement mode (face/finger) see the Supported Vital Signs Page.
