How do I scan a QRCode from a base64 image in react native?

The application consists of, through a link of a pdf, reading a QRcode and presenting its information.

For this, I put the pdf in base64 through the blob, and now I needed to go to base64 and scan the QRCode.

For this, I’m using the ‘rn-qr-generator’ library.

If you find a solution with this or another library, I would appreciate it!

if (base64) {
      // Detect QR code in image
      RNQRGenerator.detect({
        base64: `${base64}`,
      })
        .then((response) => {
          const { values } = response; // Array of detected QR code values. Empty if nothing found.
          setQRCode(values);
        })
        .catch((error) => console.log("Cannot detect QR code in image", error));
    }

Return the error:
Cannot detect QR code in image TypeError: Cannot read properties of undefined (reading ‘detect’)
