Setup

Before starting the scan process you should subscribe for events in order to receive the result from any of your scripts.

    private void OnEnable()
    {
        // Subscribe to receive event when there is an error.
        BarcodeScanner.OnErrorOccurred -= OnErrorOccurred;
        // Subscribe to receive event when usee cancelled the scan process.
        BarcodeScanner.OnScanCancelled += OnScanCancelled;
        // Subscribe to receive the result of the scan process.
        BarcodeScanner.OnBarcodeScanned += OnBarcodeScanned;
    }

    private void OnDisable()
    {
        // Unsubscribe from all events.
        BarcodeScanner.OnErrorOccurred -= OnErrorOccurred;
        BarcodeScanner.OnScanCancelled -= OnScanCancelled;
        BarcodeScanner.OnBarcodeScanned -= OnBarcodeScanned;
    }    

    private void OnBarcodeScanned(Barcode barcode)
    {
        // User barcode object to read the data.
    }

    private void OnScanCancelled ()
    {
        // Do something when the user cancelled the pro
    }

    private void OnErrorOccurred(string message, string errorCode)
    {
        // Error received.
    }

Once that’s done you can start the scan process by simply calling:

    BarcodeScanner.Scan();

And that’s it.
