Installation

To use this plugin, add flutterbudpay as a dependency in your pubspec.yaml file.

Then initialize the plugin preferably in the initState of your widget.

import 'package:flutterbudpay/flutterbudpay.dart';

class _ExamplePayementPageState extends State<ExamplePayementPage> {
  var publicKey = 'Add your BudPay Public Key Here';
  var secretKey = 'Add your Budpay Secret Key Here';
  final plugin = Budpay();

  @override
  void initState() {
    plugin.initialize(publicKey: publicKey,secretKey:secretKey);
  }
}

Making Payments

There are two ways of making payment with the plugin.

1. Checkout: This is the easy way; as the plugin handles all the processes involved in making a payment (except transaction initialization and verification which should be done from your backend).
2. Charge Card: This is a longer approach; you handle all callbacks and UI states.

1. Checkout (Recommended)

You initialize a charge object with an amount, email & accessCode or reference.

Charge charge = Charge()
      ..amount = 10000
      ..reference = _getReference()
       // or ..accessCode = _getAccessCodeFrmInitialization()
      ..email = '[e-mail]';
    CheckoutResponse response = await plugin.checkout(
      context context,
      method: CheckoutMethod.card, // Defaults to CheckoutMethod.selectable
      charge: charge,
    );

plugin.checkout() returns the state and details of the payment in an instance of CheckoutResponse .

2. Charge Card

You can choose to initialize the payment locally or via your backend.

Just send the payment details to plugin.chargeCard

      // Set transaction params directly in app (note that these params
      // are only used if an access_code is not set. In debug mode,
      // setting them after setting an access code would throw an error
      Charge charge = Charge();
      charge.card = _getCardFromUI();
      charge
        ..amount = 2000
        ..email = '[e-mail]'
        ..reference = _getReference()
        ..putCustomField('Charged From', 'Flutter PLUGIN');
      _chargeCard();

Validating Card Details

You are expected but not required to build the UI for your users to enter their payment details. For easier validation, wrap the TextFormFields inside a Form widget. Please check this article on validating forms on Flutter if this is new to you.

NOTE: You don't have to pass a card object to Charge. The plugin will call-up a UI for the user to input their card.

You can validate the fields with these methods:

card.validNumber

This method helps to perform a check if the card number is valid.

card.validCVC

Method that checks if the card security code is valid.

card.validExpiryDate

Method checks if the expiry date (combination of year and month) is valid.

card.isValid

Method to check if the card is valid. Always do this check, before charging the card.

card.getType

This method returns an estimate of the string representation of the card type(issuer).
