Measurement Modes 
The SDK supports two measurements modes - face measurements and finger measurements.
Face Measurement 
A face measurement is performed by facing the front (selfie) camera.
Dart
try {
    LicenseDetails licenseDetails = LicenseDetails("<ENTER_YOUR_LICENSE_KEY>");
    Session? session = await FaceSessionBuilder()
        .withImageDataListener(this)
        .withVitalSignsListener(this)
        .withSessionInfoListener(this)
        .build(licenseDetails);
} on HealthMonitorException catch(e) {
    print("Received Error. Domain: ${e.domain} Code: ${e.code}");
}Finger Measurement 
Deprecation Warning
Finger measurements are deprecated and will be removed in future versions of Binah.ai's SDK.
A finger measurement is performed by covering the rear camera of a device with a finger.
Dart
try {
    LicenseDetails licenseDetails = LicenseDetails("<ENTER_YOUR_LICENSE_KEY>");
    Session? session = await FingerSessionBuilder()
        .withImageDataListener(this)
        .withVitalSignsListener(this)
        .withSessionInfoListener(this)
        .build(licenseDetails);
} on HealthMonitorException catch(e) {
    print("Received Error. Domain: ${e.domain} Code: ${e.code}");
}
