Subfay Flutter SDK — subscriptions, in-app purchase entitlements and customer identity for your Flutter app.

Subfay Flutter SDK

Entitlements, customers and subscription state for Flutter apps, powered by Subfay.

Install

dependencies:
  subfay: ^1.0.0

Usage

import 'package:subfay/subfay.dart';

// Configure once at startup with your publishable key
await Subfay.instance.configure(
  apiKey: 'pk_live_xxxxx',
  environment: Environment.production,
);

// Identify the signed-in user
await Subfay.instance.identify(externalUserId: 'user_123');

// Gate a feature on an entitlement
if (await Subfay.instance.hasEntitlement('premium')) {
  // unlock premium
}

// React to entitlement changes
Subfay.instance.entitlementsStream.listen((entitlements) {
  print('Active entitlements: $entitlements');
});

Purchases

This SDK does not run store transactions. Take the purchase with your store plugin (e.g. in_app_purchase), send the receipt to your server, and validate it there with your secret key via POST /iap/validate. Once Subfay records the entitlement, it shows up here.
