RMSSD ​

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

The application can receive the RMSSD result by implementing VitalSignsListener:

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

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.
