// Get a reference to the barcode-scan element
const barcodeScanner = document.querySelector('barcode-scan');
// Add an event listener to capture scan results
barcodeScanner.addEventListener('scan', (event) => {
const scanResult = event.detail;
// Handle the scan result here
console.log('Scanned Barcode:', scanResult.code);
console.log('Is Valid:', scanResult.isValid);
console.log('Time Taken (ms):', scanResult.timeTakenMs);
console.log('Cleaned Code:', scanResult.cleanedCode);
});
