authnet_dart

The easiest entry point to the community-maintained Authorize.Net SDK for Dart and Flutter. One import provides typed payments, eCheck, PayPal, customer profiles (CIM), recurring billing (ARB), reporting, Accept.js, Accept Hosted, wallet token helpers, and verified webhooks.

Not affiliated with, endorsed by, or certified by Authorize.Net or Visa.

Install

dart pub add authnet_dart

import 'package:authnet_dart/authnet_dart.dart';

Quick start

final client = AuthNetClient(
  config: AuthNetConfig(
    apiLoginId: apiLoginId,
    transactionKey: transactionKey,
    environment: AuthNetEnvironment.sandbox,
  ),
);

final result = await client.charge(PaymentRequest(
  amount: 19.99,
  method: PaymentMethod.opaqueData,
  billing: BillingDetails(firstName: 'Jane', lastName: 'Doe'),
  opaqueData: OpaqueData(
    dataDescriptor: descriptor,
    dataValue: nonce,
  ),
));

if (result.isApproved) {
  print('Approved: ${result.transactionId}');
}

client.close();

For a Flutter application, obtain the one-time nonce with the exported Accept.js or Accept Hosted helpers, then send it to your backend for the charge. Never ship a production Transaction Key in a distributed app.

Umbrella or modular packages?

Use authnet_dart when you want the simplest install and expect to use more than one part of the SDK. The same APIs are also available separately:

The umbrella contains no alternate implementation: it re-exports those three packages, so moving between umbrella and modular dependencies does not require learning a second API.
