passesFromBytes static method

List<PkPass> passesFromBytes(Uint8List bytes, { bool skipChecksumVerification = false, bool skipSignatureVerification = false, })

Parses a .pkpasses to a list of PkPasses. The mimetype of that file is application/vnd.apple.pkpasses. A .pkpasses file cna contain up to ten PkPasses.

Setting skipVerification to true disables any checksum or signature verification and validation.

Implementation

// TODO(ueman): Detect whether it's maybe just a single pass, and then
// gracefully fall back to just parsing the PkPass file.
// TODO(ueman): Provide an async method for this.

  }

  final archive = decoder.decodeBytes(bytes);
