v4.12.0

Features

• Add onScanFrameData option that allows an app to obtain an image of the video stream at the point
  in time a code was scanned, which can be useful for driving UIs. It accepts a callback function
  that is called with the base64 image data in the chosen imageConversion format:

  const opts = {
    filter: { method, type },
    containerId,
    onScanFrameData: (base64) => {
      // Show the frame at the point of decode
      img.src = base64;
    },
  };
  
  const res = await operator.scanStream(opts);
  console.log(res);

  If the autoStop: false option is used, then this callback is called for each successive scan.
