+# pkpass
+
+A Dart native pkpass parsing library
+
+## Features
+
+- no platform specific dependencies - pure Dart
+- parse any .pkpass file as blob
+- extract metadata
+- high level lookup for assets by locale and scale, with proper fallbacks
+
+## Getting started
+
+```dart
+import 'dart:io';
+
+import 'package:intl/locale.dart';
+import 'package:pkpass/pkpass.dart';
+
+Future<int> main(List<String> args) async {
+  print('Using first argument or stdin file name: ');
+  final path = args.singleOrNull ?? stdin.readLineSync();
+  if (path == null || path.isEmpty) {
+    print('Please enter a file name or provide it as single argument.');
+    return 1;
+  }
+
+  final file = File(path);
+  final contents = await file.readAsBytes();
+
+  final pass = await PassFile.parse(contents);
+
+  final logo = pass.getLogo(
+    scale: 2,
+    locale: Locale.fromSubtags(languageCode: 'fr'),
+  );
+
+  print('Logo image blob length: ${logo?.length}');
+
+  return 0;
+}
+
+```
