Since: ArcGIS Maps SDK for JavaScript 4.19

The BarcodeScannerInput class defines the desired user interface for a barcode or QR code scanner. If this input type is used in an ArcGIS Maps SDK for JavaScript web application, it will default to the TextBoxInput type as the API does not currently support bar code scanning.
