/**
 * @name Braintree
 * @capacitorincompatible true
 * @description
 * This plugin enables the use of the Braintree Drop-In Payments UI in your Ionic applications on Android and iOS, using the native Drop-In UI for each platform (not the Javascript SDK).
 *
 *  Ionic Native utilizes [a maintained fork](https://github.com/taracque/cordova-plugin-braintree) of the original `cordova-plugin-braintree`
 *
 *  For information on how to use Apple Pay with this plugin, please refer to the [plugin documentation](https://github.com/Taracque/cordova-plugin-braintree#apple-pay-ios-only)
 *
 * **NOTE**: This is not a complete payments solution. All of the Braintree client-side UIs simply generate a payment nonce that must then be processed by your server to complete the payment.
 * See the [Braintree Node server documentation](https://developers.braintreepayments.com/start/hello-server/node) for details and a [sample Express server](https://github.com/braintree/braintree_express_example) that implements the required functionality.
 *
 * @usage
 * ```typescript
 * import { Braintree, ApplePayOptions, PaymentUIOptions } from '@ionic-native/braintree/ngx';
 *
 * constructor(private braintree: Braintree) { }
 *
 * ...
 *
 * // Your Braintree `Tokenization Key` from the Braintree dashboard.
 * // Alternatively you can also generate this token server-side
 * // using a client ID in order to allow users to use stored payment methods.
 * // See the [Braintree Client Token documentation](https://developers.braintreepayments.com/reference/request/client-token/generate/node#customer_id) for details.
 * const BRAINTREE_TOKEN = '<YOUR_BRAINTREE_TOKEN>';
 *
 * // NOTE: Do not provide this unless you have configured your Apple Developer account
 * // as well as your Braintree merchant account, otherwise the Braintree module will fail.
 * const appleOptions: ApplePayOptions = {
 *   merchantId: '<YOUR MERCHANT ID>',
 *   currency: 'USD',
 *   country: 'US'
 * }
 *
 * const paymentOptions: PaymentUIOptions = {
 *   amount: '14.99',
 *   primaryDescription: 'Your product or service (per /item, /month, /week, etc)',
 * }
 *
 * this.braintree.initialize(BRAINTREE_TOKEN)
 *   .then(() => this.braintree.setupApplePay(appleOptions))
 *   .then(() => this.braintree.presentDropInPaymentUI(paymentOptions))
 *   .then((result: PaymentUIResult) => {
 *     if (result.userCancelled) {
 *       console.log("User cancelled payment dialog.");
 *     } else {
 *       console.log("User successfully completed payment!");
 *       console.log("Payment Nonce: " + result.nonce);
 *       console.log("Payment Result.", result);
