Initialize Xendit:

import 'package:fxendit/fxendit.dart';

Xendit xendit = Xendit('your_xendit_public_key');

Create a Single Use Token.

XCard card = XCard(
  creditCardNumber: '4111111111111111',
  creditCardCVN: '123',
  expirationMonth: '09',
  expirationYear: '2021',
);

TokenResult result = await xendit.createSingleUseToken(
  card,
  amount: 75000,
  shouldAuthenticate: true,
  onBehalfOf: '',
);

if (result.isSuccess) {
  tokenId = result.token!.id;
  print('Token ID: ${result.token!.id}');
} else {
  print('SingleUseToken Error: ${result.errorCode} - ${result.errorMessage}');
}

Create a Multiple Use Token.

XCard card = XCard(
  creditCardNumber: '4111111111111111',
  creditCardCVN: '123',
  expirationMonth: '09',
  expirationYear: '2021',
);

TokenResult result = await xendit.createMultipleUseToken(card);

if (result.isSuccess) {
  tokenId = result.token!.id;
  print('Token ID: ${result.token!.id}');
} else {
  print('MultipleUseToken Error: ${result.errorCode} - ${result.errorMessage}');
}

Create a 3DS Authentication.

AuthenticationResult result = await xendit.createAuthentication(tokenId, amount: 50000);

if (result.isSuccess) {
  print('Authentication ID: ${result.authentication!.id}');
} else {
  print('Authentication Error: ${result.errorCode} - ${result.errorMessage}');
}

Check if a credit card number is valid.

String cardNumber = '4111111111111111';

bool isValid = CardValidator.isCardNumberValid(cardNumber);

String expirationMonth = '09';
String expirationYear = '2021';

bool isValid = CardValidator.isExpiryValid(expirationMonth, expirationYear);

String cardCVN = '123';

bool isValid = CardValidator.isCvnValid(cardCVN);

Get card type based on card number.

String cardNumber = '4111111111111111';

print('${cardType.cardName} - ${cardType.cardKey}');

Check if the card CVN length is valid for its type.

String cardNumber = '4111111111111111';
String cardCVN = '123';

bool isValid = CardValidator.isCvnValidForCardType(cardCVN, cardNumber);
