Problem Statement

Hello, I have an issue when im making an Apple Wallet app.

I've created the pkpass file succesfully but when i try to add it to Wallet i have an error.

Error;
flutter: Error: PlatformException(invalid, Received data is not a valid PKPass, The pass cannot be read because it isn’t valid., null) 

How I create the pkpass file; Stars added for privacy by me on app there are no stars.

 // Generate PkPass file
      final pass = PkPass(
        pass: PassData(
          formatVersion: 1, // Certificate
          passTypeIdentifier: 'pass.nl.twogomobile.flutterwalletapp',
          serialNumber: 'XI****-PASS-2255', // Certificate
          description: 'Test',
          organizationName: 'Test App',
          teamIdentifier: 'PT6K******',
          barcode: Barcode(
            message: '123456789',
            format: PkPassBarcodeType.qr,
            messageEncoding: 'iso-8859-1',
          ),
        ),

        icon: PkImage(image1: iconBytes, image2: icon2XBytes),
        logo: PkImage(image1: logoBytes),
      );

      // .pkpass generate
      Uint8List? binaryData = pass.write(
        certificatePem: certificatePem,
        privateKeyPem: privateKeyPem,
      );

      // .pkpass write the file.
      final pkPassPath = '${directory.path}/pass.pkpass';
      File(pkPassPath).writeAsBytesSync(binaryData!);

How i read and try to add on Wallet;

      // .pkPass dosyasını oku
      Uint8List pkPassUint8 = File(pkPassPath).readAsBytesSync();



      // first check whether PassKit is available
      bool isAvailable = await passKit.isPassLibraryAvailable();
      // then check whether you can actually add passes
      bool canAddPasses = await passKit.canAddPasses();

      // when both of them are true, you can add a pass.
      if(isAvailable && canAddPasses) {
        await passKit.addPass(pkPassUint8);
      }

  icon: PkImage(image1: iconBytes, image2: icon2XBytes),
  logo: PkImage(image1: logoBytes),
);

Is that the whole data you add to the pass? If so, that's most likely the reason, since that can't result in a valid pass.

Hey again! Thank for your quick answer! yeah we created it for test app before intergrate to the main app. Could you please provide me a correct passData? I would be really happy about it.

Apple has a couple examples here.

Alternatively, take a look at the links here: #23

Hey! thanks for your all informations. We successfully got the view for the Wallet Add. But when we add nfc(we need to use it) I still get same error. Do i have to pass a "encryptionPublicKey"? is it neccessary?

        nfc: Nfc(
          message: 'Test Value',
          requiresAuthentication: false,
        ),

Unfortunately, I can't help you with that. I don't have any access to things needed to create or test NFC passes. If you figure it out, please let me know

[ueman]

@Latth Do you use a NFC Pass Type Identifier Certificate and a NFC pass type identifier? Your company probably needs to get some special permit from Apple for it

[ueman]

Note to self: Write a disclaimer for NFC passes in the readme

Hello! i am just testing on myself rigjt now. on emulator, still doesnt work for me. Did you find something more about it?

[ueman]

No, if you or anyone else can provide me with a valid NFC certificate and so on, I can try looking into it. Without those things there's nothing I can do.

You can try generating NFC enabled passes with some other software that's out there (there's a good JS based software out there) and compare it to what this package does. Maybe that gives you some pointers to try to fix things.
