Moyasar Widgets

import 'package:flutter/material.dart';
import 'package:moyasar/moyasar.dart';

class PaymentMethods extends StatelessWidget {
  PaymentMethods({super.key});

  final paymentConfig = PaymentConfig(
    publishableApiKey: 'YOUR_API_KEY',
    amount: 25758, // SAR 257.58
    description: 'order #1324',
    metadata: {'size': '250g'},

  );

  void onPaymentResult(result) {
    if (result is PaymentResponse) {
      switch (result.status) {
        case PaymentStatus.paid:
          // handle success.
          break;

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [

  }
}

Custom Widgets

// Unified config for Moyasar API
  final paymentConfig = PaymentConfig(
    publishableApiKey: 'YOUR_API_KEY',
    amount: 25758, // SAR 257.58
    description: 'order #1324',
    metadata: {'size': '250g'},
    creditCard: CreditCardConfig(saveCard: true, manual: false),

        merchantId: 'YOUR_MERCHANT_ID',
        label: 'YOUR_STORE_NAME',
        manual: false),
  );

  // Callback once the user clicks on the custom Apple Pay widget
  void onSubmitApplePay(applePay) async {
    final source = ApplePayPaymentRequestSource(
        applePay['token'], (paymentConfig.applePay as ApplePayConfig).manual);
    final paymentRequest = PaymentRequest(paymentConfig, source);

    final result = await Moyasar.pay(
        apiKey: paymentConfig.publishableApiKey,
        paymentRequest: paymentRequest);

    onPaymentResult(result);
  }

  // Callback once the user fills & submit their CC information using the custom form widget
  void onSubmitCcForm() async {
    final source = CardPaymentRequestSource(
        creditCardData: CardFormModel(
            name: 'John Doe',
            number: '4111111111111111',
            month: '05',

    final result = await Moyasar.pay(
        apiKey: paymentConfig.publishableApiKey,
        paymentRequest: paymentRequest);

    onPaymentResult(result);
  }

  // Unified payment result processor
  void onPaymentResult(result) {
    if (result is PaymentResponse) {
      switch (result.status) {
        case PaymentStatus.initiated:
          // handle 3DS redirection.
          break;
        case PaymentStatus.paid:
          // handle success.
          break;
        case PaymentStatus.failed:

          break;
      }
    }

Testing

Credit Cards

Moyasar provides a sandbox environment for testing credit card payments without charging any real money. This allows you to test your integration and ensure that everything is working correctly before going live with actual payments. Learn more about our testing cards here

Apple Pay

Testing using a simulator will not work! Learn more about Apple Pay testing here.

    publishableApiKey: 'YOUR_API_KEY',
    amount: 25758, // SAR 257.58
    description: 'order #1324',
    metadata: {'size': '250g'},
