How to get information in my qr code and display it in add new contact automatically

I am developing a Flutter mobile app for business cards and I have an issue. After scanning a QR code in my application, how can I get the information from the QR code and display it in the 'Add New Contact' automatically on the scanner phone? i work with qr_flutter package

   string qrdata=   {   "fname": 'AOUICHE Redouane',"adr":'vdsv', "phone":'00000',   "job":'IT admin specialiste',  
"email":'r.aouiche@exwor.net',   }   ''';

 Align(
          child: Center(
            child: SingleChildScrollView(
              child: Column(
                children: [
                  QrImageView(
                    data: qrData.toString(),
                    size: 200,
                    backgroundColor: Colors.white,
                    version: QrVersions.auto,
                  ),
                ],
              ),
            ),
          ),
        ),

QR codes used for contact sharing often follow the vCard :

example of vCard :

BEGIN:VCARD
VERSION:3.0
FN:John Doe
TEL:+1234567890
EMAIL:johndoe@example.com
END:VCARD

Code :

String qrdata = '''
BEGIN:VCARD
VERSION:3.0
FN:AOUICHE Redouane
TEL:+1200000
EMAIL:r.aouiche@exwor.net
END:VCARD
''';



return Align(
          child: Center(
            child: SingleChildScrollView(
              child: Column(
                children: [
                  QrImageView(
                    data: qrData.toString(),
                    size: 200,
                    backgroundColor: Colors.white,
                    version: QrVersions.auto,
                  ),
                ],
              ),
            ),
          ),
        ),

You just need to implement this code for QR scanning, and it will automatically display the option to add the contact.
