yandex_pay_core

Core SDK for the Yandex Pay Flutter modular architecture. Provides:

• YPay — singleton for initialization, locale/theme updates, and lifecycle (initialize, updateConfiguration, clear).
• ModuleRegistry — extension point used by flow modules (yandex_pay_quickpay, yandex_pay_auth, future modules) to register themselves with core.
• Deeplink handling — YPay.instance.deeplinkHandler.handleOpenURL / handleUserActivity (iOS) and Android intent forwarding.
• Shared models — YPayEnvironment, YPayLocale, YPayTheme, YPayMerchant.

Most apps do not depend on this package directly. Add a flow module (e.g. yandex_pay_quickpay) and yandex_pay_core comes transitively.

Usage

import 'package:yandex_pay_core/yandex_pay_core.dart';
import 'package:yandex_pay_quickpay/yandex_pay_quickpay.dart';

await YPay.initialize(
  environment: YPayEnvironment.sandbox,
  modules: [
    quickPayModule(merchantId: 'your-merchant-id'),
  ],
);

Companion packages

• yandex_pay_quickpay — QuickPay flow (payment methods widget, active method badge, expandable widget).
• yandex_pay_auth — optional auth module (authorize, logout, auth state stream).
