Take a look at the integration requirements.
Sign up to the business console and create an account.

Installation

This adds the pay package to the list of dependencies in your pubspec.yaml file with the following command:

flutter pub add pay

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
}
