payorc_flutter_v2 1.0.7

A Flutter plugin for orc payment.

payorc_flutter_v2

Flutter SDK for PayOrc checkout: payment method sheet (Apple Pay, Google Pay, Tabby, Samsung Pay, pay with card), add-card flow, and related UI. Merchant keys and the PayOrc service SDK drive checkout customization (colors, available methods, wallet JSON).

Requirements

• Flutter SDK compatible with this package’s pubspec.yaml constraints.
• Merchant keys and the PayOrc service SDK drive checkout customization (colors, available methods, wallet JSON). Tabby credentials are returned by POST .../sdk/tabby/init when Tabby is enabled in checkout.

Installation

Add the dependency (path or pub.dev version):

dependencies:
  payorc_flutter_v2: ^1.0.7

import 'package:payorc_flutter_v2/payorc_flutter_v2.dart';

App setup (required for toasts / alerts)

The SDK uses BotToast for some alerts. Wrap your app and register observers once:

import 'package:payorc_flutter_v2/payorc_flutter_v2.dart';

runApp(
  PayorcRoot(
    child: MaterialApp(
      navigatorObservers: [
        ...PayorcSdk.botToastNavigatorObservers,
      ],
      home: const MyHomePage(),
    ),
  ),
);

Alternative: keep your existing MaterialApp and compose PayorcSdk.wrapMaterialAppBuilder into MaterialApp.builder (see API docs on PayorcSdk.wrapMaterialAppBuilder).

---

1. PayorcSdk.init — configure the SDK

Call once at startup (before PayorcSdk.instance or any sheet). Loads checkout customization in the background when the default internal flags apply (see implementation).

PayorcSdk.init(
  merchantKey: 'YOUR_MERCHANT_KEY',
  merchantSecret: 'YOUR_MERCHANT_SECRET',
  environment: PayorcEnvironment.sandbox, // or PayorcEnvironment.production
  language: PayorcLanguage.english,      // optional; default english
);

Parameters

Parameter	Type	Required	Description
merchantKey	String	yes	PayOrc merchant key.
merchantSecret	String	yes	PayOrc merchant secret.
environment	PayorcEnvironment	yes	sandbox or production API / gateway behavior.
language	PayorcLanguage	no	SDK language / text direction (english, arabic). Default english.

Tabby is enabled when checkout customization includes Tabby in the payment sequence. The SDK calls POST .../sdk/tabby/init at checkout time; TabbyInitData.password is the Tabby API key and TabbyInitData.merchantCode is the Tabby merchant code — do not pass these to PayorcSdk.init.

Return value

Returns the configured PayorcSdk singleton. After init, use PayorcSdk.instance anywhere.

---

2. PayorcSdk.customization — host UI overrides

Optional static call (any time after init) to override checkout-driven colors and form chrome.

Priority: each non-null argument you pass wins over checkout merchant_details from the customization API. Omitted arguments keep the previous host override (if any), then the API value, then SDK defaults. Nested objects (button, text, addCardForm, appTextField, bottomSheet) merge field-by-field: only non-null properties apply.

Calling customization bumps PayorcSdk.uiCustomizationRevision and PayorcSdk.checkoutCustomizationRevision, so widgets such as AppTextField rebuild.

Checkout API mapping (merchant_details)

customization parameter	Checkout field
inputBorderStyle	field_border (outline / underline)
appBarStyle	app_style (nativeIos / nativeAndroid)
textPrimary or text.primary	text_primary
textSecondary or text.secondary	text_secondary
autoselectColor	autoselect_color

| appTextField.borderColor | border_color (field strokes only) |

guidanceStyle is host-only (not from checkout).

3. Checkout — two ways to submit an order

There are two integration paths. Both end with PayOrc.submitOrder for card payments (3DS / gateway sheet). Wallets (Apple Pay, Google Pay) and Tabby complete inside their own SDK flows when you use the built-in UI or embedded widgets.

	Way 1 — SDK UI	Way 2 — Your own UI
Entry	PayorcSdk.instance.showOptionsSheet	Embedded widgets and/or PayOrc helpers
Who builds the screen	PayOrc payment-options sheet	You place buttons/tiles in your layout
Card checkout	You call PayOrc.submitOrder from onAddNewCard	Same — call PayOrc.submitOrder (or use embeds that call it for you)

Way 1 — showOptionsSheet (full SDK UI)

Use this when you want the payment method bottom sheet (Apple Pay, Google Pay, Tabby, Samsung Pay, pay with card) with minimal custom UI.

1. Build a submit-order PaymentRequest (paymentToken, order/customer/billing/shipping, urls, etc.).
2. Call PayorcSdk.instance.showOptionsSheet with that request.
3. When the user adds or confirms a card, onAddNewCard receives CardData including paymentToken (from add-card / verification). That token is required for PayOrc.submitOrder.
4. After the options sheet closes, schedule submit on the next frame (avoids presenting a modal while the sheet is still popping):

import 'package:payorc_flutter_v2/payorc_flutter_v2.dart';

Future<void> _startPayorcCheckout(BuildContext context) async {
  final request = PaymentRequest.submitOrder(
    // paymentToken, orderDetails, customerDetails, billingDetails,
    // shippingDetails, urls, …
  );

  await PayorcSdk.instance.showOptionsSheet(
    context,
    paymentRequest: request,
    onAddNewCard: (CardData input) {
      if (!context.mounted) return;
      WidgetsBinding.instance.addPostFrameCallback((_) {
        _submitPayorcOrder(context, input, request);
      });
    },
    onApplePayResult: (result) { /* wallet payload */ },
    onGooglePayResult: (result) { /* wallet payload */ },
    onPaymentError: (error) { /* wallet / flow errors */ },
    onTabbyAuthorized: () { /* Tabby OK */ },
    onTabbyError: (error) { /* Tabby error */ },
  );
}

void _submitPayorcOrder(
  BuildContext context,
  CardData card,
  PaymentRequest request,
) {
  PayOrc.submitOrder(
    context,
    card: card,
    paymentRequest: request,
    onSuccessPayment: (_) {
      if (!context.mounted) return;
      // Payment succeeded — navigate, refresh order, etc.
    },
    onPaymentFailed: (submitModalContext, message, {code}) {
      if (!context.mounted) return;
      // Optional analytics; SDK still shows failure / retry UI
    },
    onRetryPayment: () {},
  );
}

Notes

• onAddNewCard is required — the sheet does not call PayOrc.submitOrder for you; your app must continue checkout with the returned CardData.
• On payment failure, PayOrc.submitOrder shows the SDK failure sheet (Retry, Add new card, Use another card) and re-opens submit-order internally — you do not pass an onNewCardAdded callback.
• Apple Pay / Google Pay / Tabby use the callbacks on showOptionsSheet (or embedded equivalents); card rail always goes through PayOrc.submitOrder.

Way 2 — Your own UI (embedded widgets + PayOrc)

Use this when you do not want the full payment-options sheet and instead embed PayOrc controls in your checkout screen.

• Option A — All-in-one — PayorcEmbeddedPaymentCheckout (wallets + tiles in checkout order; see §5).
• Option B — Individual embeds — compose PayorcEmbeddedApplePayButton, Google Pay, Tabby, Samsung, pay-with-card, etc. (see §5).
• Option C — PayOrc helpers only — full control over when sheets open (lib/payorc.dart):

// Add card only (WebView verification); card may include paymentToken in onAddCard
await PayOrc.addNewCard(
  context,
  paymentRequest: PaymentRequest.deriveForAddCard(submitOrderRequest),
  onAddCard: (sheetContext, card) {
    Navigator.of(sheetContext).pop();
    PayOrc.submitOrder(
      context,
      card: card,
      paymentRequest: submitOrderRequest,
      onSuccessPayment: (_) { /* success */ },
    );
  },
);

// Or submit when you already have CardData (e.g. saved card + CVV from your UI)
await PayOrc.submitOrder(
  context,
  card: card,
  paymentRequest: submitOrderRequest,
  onSuccessPayment: (_) { /* … */ },
);

See PayOrc — add card & submit order for parameter details.

4. PayorcSdk.instance.showOptionsSheet — payment method bottom sheet

Presents the payment options flow (Way 1 above): refreshes checkout customization, then shows Apple Pay / Google Pay / Tabby / Samsung Pay / pay-with-card, depending on your PayOrc configuration.

await PayorcSdk.instance.showOptionsSheet(
  context,
  paymentRequest: request,
  onAddNewCard: (CardData input) {
    // Card includes paymentToken — call PayOrc.submitOrder on the next frame (see §3).
  },
  onApplePayResult: (Map<String, dynamic> result) {
    // Wallet token payload from the `pay` package (debug / integrate as needed).
  },
  onGooglePayResult: (Map<String, dynamic> result) {
    // Same for Google Pay.
  },
  onPaymentError: (Object? error) {
    // Apple Pay / Google Pay or flow errors.
  },
  onTabbyAuthorized: () {
    // Tabby authorized (if Tabby enabled).
  },
  onTabbyError: (Object? error) {
    // Tabby rejected / error.
  },
);

5. Embedded payment methods

Use these when building your own checkout UI (Way 2). All widgets are exported from payorc_flutter_v2.dart (embedded_payorc_payment_widgets.dart, payorc_embedded_tabby_button.dart).

Prerequisites

1. Call PayorcSdk.init before building embeds.
2. Wrap your app with PayorcRoot (see App setup) so SDK theme, fonts, and toasts work.
3. Pass a submit-order PaymentRequest (PaymentRequest.submitOrder, same shape as showOptionsSheet).
4. Checkout customization must be loaded (happens on init / first sheet refresh). Widgets listen to PayorcSdk.checkoutCustomizationRevision and hide themselves when a method is not enabled (SizedBox.shrink()).

Visibility

Widget	Shown when
PayorcEmbeddedApplePayButton	iOS, Apple Pay in checkout sequence, device can pay
PayorcEmbeddedGooglePayButton	Android, Google Pay config available
PayorcEmbeddedTabbyButton	Tabby enabled in checkout customization
payorcEmbeddedSamsungPayTile	Samsung Pay in checkout sequence
payorcEmbeddedOpenPayWithCard	checkoutRequest.kind == submitOrder

Compose your checkout screen

import 'package:payorc_flutter_v2/payorc_flutter_v2.dart';

class CheckoutPaymentSection extends StatelessWidget {
  const CheckoutPaymentSection({super.key, required this.request});

  final PaymentRequest request; // PaymentRequest.submitOrder(...)

  @override
  Widget build(BuildContext context) {
    return Column(
      crossAxisAlignment: CrossAxisAlignment.stretch,
      children: [
        PayorcEmbeddedApplePayButton(
          paymentRequest: request,
          onPaymentSuccess: (response, rawFromPayPackage) {
            // /sdk/payment succeeded
          },
          onPaymentError: (e) {
            // Wallet, parse, network, or payment API error
          },
        ),
        const SizedBox(height: 12),
        PayorcEmbeddedGooglePayButton(
          paymentRequest: request,
          onGooglePayResult: (result) {
            // Raw token map from the `pay` package — wire to your backend if needed
          },
          onPaymentError: (e) {},
        ),
        const SizedBox(height: 12),
        PayorcEmbeddedTabbyButton(
          paymentRequest: request,
          onTabbyAuthorized: () {},
          onTabbyError: (e) {},
        ),
        const SizedBox(height: 12),
        payorcEmbeddedOpenPayWithCard(
          context: context,
          checkoutRequest: request,
          onSuccessPayment: (_) {},
          onPaymentFailed: (_, message, {code}) {},
        ),

Core types

• PaymentRequest — Build with PaymentRequest.submitOrder(...) or PaymentRequest.addCard(...), or derive add-card from checkout with PaymentRequest.deriveForAddCard. See lib/data/models/payment_request.dart.
• CardData — Cardholder, expiry, CVV, optional email/phone, tokens for saved cards. See lib/data/models/card_data.dart.
• PayorcSdk.instance — Throws if PayorcSdk.init was not called; use PayorcSdk.isInitialized to guard.

PayOrc — add card & submit order (without the full sheet)

PayOrc is exported from payorc_flutter_v2.dart. Use it for Way 2 or as the submit step after Way 1 (onAddNewCard).

PayOrc.addNewCard

Opens the add-card bottom sheet (AddCardForm): signed add-card API, optional WebView verification. onAddCard receives the sheet BuildContext and CardData (often with paymentToken after success).

Parameter	Type	Description
context	BuildContext	Host context for the modal.
paymentRequest	PaymentRequest	Add-card payload (PaymentRequest.addCard or deriveForAddCard).
onAddCard	void Function(BuildContext, CardData)	Required. Card entered / verified.
onCancel	void Function(BuildContext)?	Defaults to Navigator.pop.
initialCard	CardData?	Pre-fill or edit saved card.
savedCardEditMode	bool	Edit UI for saved card (read-only PAN).
recoveryErrorCode / recoveryErrorMessage	String?	Re-open after mobile/email validation errors (E0021 / 43).

PayOrc.submitOrder

Opens the non-dismissible submit-order bottom sheet (SubmitOrder): signed POST /sdk/payment, 3DS / gateway handling, then a success confirmation sheet.

On payment failure the SDK (on the next frame) shows PaymentFailedSheetAction with:

User action	SDK behavior
Retry	Calls optional onRetryPayment, then re-opens submit-order with the same card.
Add new card	Opens add-card (using the same submit-order paymentRequest), then re-opens submit-order with the new CardData.
Use another card	Lets the user pick a saved card, then re-opens submit-order with that card.

You do not implement onNewCardAdded — failure recovery is handled inside the SDK.

await PayOrc.submitOrder(
  context,
  card: card, // CardData with paymentToken for new-card checkout
  paymentRequest: submitOrderRequest,
  mountedCheckContext: context, // optional; used for mounted checks (defaults to context)
  onSuccessPayment: (submittingContext) {
    // User dismissed the success confirmation sheet
  },
  onPaymentFailed: (submitModalContext, message, {code}) {
    // Optional — runs before SDK shows the failure sheet (analytics, logging)
  },
  onRetryPayment: () {
    // Optional — user tapped Retry on the failure sheet
  },
);

Parameter	Type	Required	Description
context	BuildContext	yes	Host context used to present the submit-order modal.
card	CardData	yes	Card to charge. New-card flow needs paymentToken on CardData (from add-card / onAddNewCard).
paymentRequest	PaymentRequest	yes	Submit-order payload (PaymentRequestType.submitOrder). Also used for failure-sheet saved cards and Add new card.
onSuccessPayment	void Function(BuildContext)?	no	Called when the user finishes the success confirmation sheet; receives submit-order sheet context.
mountedCheckContext	BuildContext?	no	Context checked with mounted before showing failure UI (defaults to context).
onPaymentFailed	void Function(BuildContext submitModalContext, String message, {String? code})?	no	Optional hook when /sdk/payment fails; SDK still presents failure / retry UI.
onRetryPayment	VoidCallback?	no	Optional hook when the user taps Retry; SDK re-presents submit-order afterward.

Returns Future<void> that completes when the submit-order modal is dismissed.
