• Drop-in UI for payment processing
• 3D Secure authentication support
• Support for saved payment methods

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_ryft_payment: ^0.1.0

Then run:

flutter pub get

Android Setup

Ensure your minimum SDK version is set to 21 or higher in your android/app/build.gradle file:

defaultConfig {
    minSdkVersion 21
    // ...
}

iOS Setup

Ensure your minimum deployment target is set to iOS 12.0 or higher in your ios/Podfile:

If you want to use Apple Pay, you'll need to add the necessary entitlements to your iOS app.

Usage

Initializing the SDK

Initialize the SDK as early as possible in your app, typically in the main.dart file:

import 'package:flutter_ryft_payment/flutter_ryft_payment.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  await RyftPayment().initialize(
    publicApiKey: 'your_ryft_public_api_key',
  );
  
  runApp(MyApp());
}

Showing the Drop-in Payment UI

To show the drop-in payment UI:

import 'dart:io';
import 'package:flutter_ryft_payment/flutter_ryft_payment.dart';

Future<void> showPaymentForm() async {
  try {
    final config = RyftPaymentConfiguration(
      clientSecret: 'your_client_secret', // Get this from your backend
      subAccountId: 'optional_sub_account_id', // Optional
      collectCardholderName: true, // Whether to collect cardholder name
      // Configure Apple Pay for iOS
      applePayConfig: Platform.isIOS ? RyftApplePayConfiguration(
        merchantIdentifier: 'merchant.com.yourcompany',
        merchantName: 'Your Company',
        merchantCountryCode: 'US',
      ) : null,
      // Configure Google Pay for Android
      googlePayConfig: Platform.isAndroid ? RyftGooglePayConfiguration(
        merchantName: 'Your Company',
        merchantCountryCode: 'US',
      ) : null,
    );

    final result = await RyftPayment().showDropIn(config: config);
    
    // Handle the result
    switch (result.status) {
      case RyftPaymentResultStatus.approved:
        print('Payment approved: ${result.paymentSession}');
        break;
      case RyftPaymentResultStatus.failed:
        print('Payment failed: ${result.errorMessage}');
        break;
      case RyftPaymentResultStatus.cancelled:
        print('Payment cancelled');
        break;
      case RyftPaymentResultStatus.requiresAction:
        print('Payment requires additional action');
        break;
    }
  } catch (e) {
    print('Error showing payment form: $e');
  }
}

      expiryMonth: '12',
      expiryYear: '2025',
      cvc: '123',
      cardholderName: 'John Doe', // Optional
      storeCard: false, // Whether to store the card for future payments
    );
    
    final result = await RyftPayment().processCardPayment(
      clientSecret: 'your_client_secret',
      paymentMethod: paymentMethod,
      subAccountId: 'optional_sub_account_id', // Optional
    );

    final result = await RyftPayment().processSavedPaymentMethod(
      clientSecret: 'your_client_secret',
      paymentMethod: paymentMethod,
      subAccountId: 'optional_sub_account_id', // Optional
