PayEngine SDK for Flutter

The PayEngine Flutter SDK allows you to build delightful payment experiences in your native Android and iOS apps using Flutter. We provide powerful and customizable UI screens and elements that can be used out-of-the-box to collect your users' payment details

Getting Started

PayEngine config

final PayEngineConfig config = const PayEngineConfig(
      publicKey: "pk_test_xxx",
      scriptURL: "https://console.payengine.dev");
final String merchantId = "<your-merchant-id>";

Credit Card Form

var additionalFields = List<PayEngineField>.from([
      PayEngineField('address_zip', 'text', 'Zip Code', true,
          keyboardType: PayEngineKeyboardType.number,
          pattern:
              r"^(?:\d{5}(?:-\d{4})?|[ABCEGHJKLMNPRSTVXY]\d[A-Z] ?\d[A-Z]\d)$"),
    ]);

final creditCardForm = CreditCardForm(config: payengineConfig, additionalFields: additionalFields);

Container(padding: const EdgeInsets.all(10), child: creditCardForm),

OutlinedButton(
    onPressed: () async {
      final response = await creditCardForm.tokenize(merchantId);
      setState(() {
        result = response;
      });
    },
    child: const Text('Tokenize')),

Bank Account Form

final bankAccountForm = BankAccountForm(config: payengineConfig);

Container(padding: const EdgeInsets.all(10), child: bankAccountForm),
OutlinedButton(
    onPressed: () async {
      final response = await bankAccountForm.tokenize(merchantId);
      setState(() {
        result = response;
      });
    },
    child: const Text('Tokenize')),
