/**
 * @class
 *
 * <h3 class="comment-api-title">Overview</h3>
 *
 * The <code>BarcodeScannerDialog</code> component provides barcode scanning functionality for all devices that support the <code>MediaDevices.getUserMedia()</code> native API.
 * Opening the dialog launches the device camera and scans for known barcode formats.
 * <br>
 * <br>
 * A <code>scanSuccess</code> event fires whenever a barcode is identified
 * and a <code>scanError</code> event fires when the scan failed (for example, due to missing permisions).
 * <br>
 * <br>
 * Internally, the component  uses the zxing-js/library third party OSS.
 *
 * For a list of supported barcode formats, see the <ui5-link target="_blank" href="https://github.com/zxing-js/library">zxing-js/library</ui5-link> documentation.
