    Extra optional configuration in start() method

    Configuration object that can be used to configure both the scanning behavior and the user interface (UI). Most of the fields have default properties that will be used unless a different value is provided. If you do not want to override anything, you can just pass in an empty object {}.

    Scanning only specific formats

    By default, both camera stream and image files are scanned against all the supported code formats. Both Html5QrcodeScanner and Html5Qrcode classes can be configured to only support a subset of supported formats. Supported formats are defined in enum Html5QrcodeSupportedFormats. I recommend using this only if you need to explicitly omit support for certain formats or want to reduce the number of scans done per second for performance reasons.

    The library now supports some experimental features which are supported in the library but not recommended for production usage either due to limited testing done or limited compatibility for underlying APIs used. Read more about it here. Some experimental features include:

    •Support for BarcodeDetector JavaScript API

    1.Code changes should only be made to /src only.
