Package validator #
Naming conflicts is a common issue for private registry. A reasonable solution is to add prefix to reduce conflict probability.
With uploadValidator you could check if uploaded package is valid.
var app = unpub.App(
// ...
uploadValidator: (Map<String, dynamic> pubspec, String uploaderEmail) {
// Only allow packages with some specified prefixes to be uploaded
var prefix = 'my_awesome_prefix_';
var name = pubspec['name'] as String;
if (!name.startsWith(prefix)) {
throw 'Package name should starts with $prefix';
}

// Also, you can check if uploader email is valid
if (!uploaderEmail.endsWith('@your-company.com')) {
throw 'Uploader email invalid';
}
}
);

Customize meta and package store #
Unpub is designed to be extensible. It is quite easy to customize your own meta store and package store.
import 'package:unpub/unpub.dart' as unpub;

class MyAwesomeMetaStore extends unpub.MetaStore {
// Implement methods of MetaStore abstract class
// ...
}

class MyAwesomePackageStore extends unpub.PackageStore {
// Implement methods of PackageStore abstract class
// ...
}

// Then use it
var app = unpub.App(
metaStore: MyAwesomeMetaStore(),
packageStore: MyAwesomePackageStore(),
);
