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:

Dart

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

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

For a list of supported vital signs by platform and measurement mode (face/polar), along with their required measurement durations, refer to the Indicators Technical Information page.
