LF/HF ​

The LF/HF value is sent as part of the final results.

The application can receive the LF/HF result by implementing VitalSignsListener:

@override
void onFinalResults(VitalSignsResults results) {
    VitalSign? vitalSign = results.getResult(VitalSignTypes.lfhf);
    if (vitalSign != null && vitalSign is VitalSignLfhf) {
        VitalSignLfhf lfhf = vitalSign;
        print("LFHF: ${lfhf.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.
