🚧 API is subject to change! 🚧 The API should become a lot more stable once this package fully supports localization.

PassKit allows you to work with Apple's PkPass files. This is a pure Dart library. No Flutter needed.

In order to show PassKit files in Flutter, use the passkit_ui package, which includes ready made widgets.

Want to work with Apple's native PassKit APIs? Consider using apple_passkit.

What is PassKit?

Passes are a digital representation of information that might otherwise be printed on small pieces of paper or plastic. They let users take an action in the physical world. Passes can contain images and a barcode, and you can update passes using push notifications on iOS.

This technology consists of three main components:

  • A package format for creating passes.
  • A web service API for updating passes, implemented on your server.
  • An API used by your apps to interact with the user’s pass library.

A PkPass file looks something like this when rendered:

How to read a PassKit file?

import 'package:passkit/passkit.dart';

void main() {
  final passKitBytes = ... // get bytes for the PassKit from somewhere
  final pkPass = PkPass.fromBytes(passKitBytes);
}

How to get the latest version of a given PkPass?

import 'package:passkit/passkit.dart';

void main() {
  final passKitBytes = ... // get bytes for the PassKit from somewhere
  final pkPass = PkPass.fromBytes(passKitBytes);

  if(pkPass.isWebServiceAvailable) {
    final pkPassBytes = PassKitWebClient().getLatestVersion(pkPass);
  }
}
