Usage

To start using payment you need to get Merchant Identifier:

Use without buttons (for your design)

final MadPay pay = MadPay();

// To find out if payment is available on this device
await pay.checkPayments();

// If you need to check if user has at least one active card
await pay.checkActiveCard(
  paymentNetworks: <PaymentNetwork>[
    PaymentNetwork.visa,
    PaymentNetwork.mastercard,
  ],
);

// To pay with Apple Pay or Google Pay
await pay.processingPayment(
  PaymentRequest(
    google: GoogleParameters(
      gatewayName: 'Your Gateway',
      gatewayMerchantId: 'Your id',
      merchantId: 'example_id',
    ),
    apple: AppleParameters(
      merchantIdentifier: 'Your id',
    ),
    currencyCode: 'USD',
    countryCode: 'US',
    paymentItems: <PaymentItem>[
      PaymentItem(name: 'T-Shirt', price: 2.98),
      PaymentItem(name: 'Trousers', price: 15.24),
    ],
    paymentNetworks: <PaymentNetwork>[
      PaymentNetwork.visa,
      PaymentNetwork.mastercard,
    ],
  )
);
