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(),
);
