Usage

Define the configuration for your payment provider(s). Take a look at the parameters available in the documentation for Apple Pay and Google Pay, and explore the sample configurations in this package.

Example

This snippet assumes the existence of a payment configuration for Apple Pay (defaultApplePayConfig) and another one for Google Pay (defaultGooglePayConfig):

import 'package:pay/pay.dart';
import 'payment_configurations.dart' as payment_configurations;

const _paymentItems = [
  PaymentItem(
    label: 'Total',
    amount: '99.99',
    status: PaymentItemStatus.final_price,
  )
];

ApplePayButton(
  paymentConfiguration: payment_configurations.defaultApplePayConfig,
  paymentItems: _paymentItems,
  style: ApplePayButtonStyle.black,
  type: ApplePayButtonType.buy,
  margin: const EdgeInsets.only(top: 15.0),
  onPaymentResult: onApplePayResult,
  loadingIndicator: const Center(
    child: CircularProgressIndicator(),
  ),
),

GooglePayButton(
  paymentConfiguration: payment_configurations.defaultGooglePayConfig,
  paymentItems: _paymentItems,
  type: GooglePayButtonType.buy,
  margin: const EdgeInsets.only(top: 15.0),
  onPaymentResult: onGooglePayResult,
  loadingIndicator: const Center(
    child: CircularProgressIndicator(),
  ),
),

void onApplePayResult(paymentResult) {
  // Send the resulting Apple Pay token to your server / PSP
}

void onGooglePayResult(paymentResult) {
  // Send the resulting Google Pay token to your server / PSP
}
