Reading certificate from asset to use in PdfSignatureField

[robert.jones]

I am trying to read the pix from assets folder but do not know what file type I should use.

      if (document.form.fields[i].name == 'Signature') {

        final ByteData data =

            await rootBundle.load('assets/pfx/certificate.pfx');

        final List<int> bytes =

            data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);

        document.form.fields.add(

          PdfSignatureField(document.pages.add(), 'Sign',

              bounds: document.form.fields[i].bounds,

              signature: PdfSignature(

                  certificate: PdfCertificate(bytes, 'password123'))),

        );

      }

To perform digital signing, it is recommended to utilize a certificate that has a private key, such as a .pfx file. The user guide documentation on signing PDF documents using a .pfx file is available for your reference. https://help.syncfusion.com/flutter/pdf/working-with-digital-signature#adding-a-digital-signature
