QrBarScanResult class

A model class that represents the result of a successful barcode or QR code scan.

This class encapsulates all information from a scanned code, including the raw data value, the detected format type, and the timestamp when the scan occurred. It provides a standardized structure for handling scan results throughout the application.

Typically obtained from the onScan callback of QrBarScanView:

QrBarScanView(
  onScan: (QrBarScanResult result) {
    // Process the scan result
    print('Scanned a ${result.type.label}: ${result.value}');

    // Check the scan type and handle accordingly
    if (result.type == QrBarType.qr) {
      // Handle QR code data
      handleQrCodeData(result.value);
    } else if (result.type == QrBarType.ean13) {
      // Handle product barcode
      lookupProduct(result.value);
    }
  },
)

The class also provides a useful toString implementation for debugging and logging purposes.
