Atomic Transact for Flutter

A Flutter plugin that wraps the native Atomic Transact SDKs

Installation

Add atomic_transact_flutter as a dependency in your pubspec.yaml file:

dependencies:
  ...
  atomic_transact_flutter: <version>

iOS Requirements

• Xcode 12.0 or greater
• iOS 14.0 or greater

Android Requirements

Set the minSdkVersion in android/app/build.gradle:

android {
    defaultConfig {
        minSdkVersion 21 // or greater
    }
}

Responding to data requests

Transact emits a data request when it needs information that only your app can supply, such as card or identity details for a deferred payment method. Return an AtomicTransactDataResponse from onDataRequest and it is sent back to Transact. The handler may be asynchronous, so you can prompt the user or call your backend before responding.

Atomic.transact(
  config: config,
  onDataRequest: (request) async {
    // request.fields lists what Transact is asking for, e.g. ['card']
    final card = await promptForCard();

    return AtomicTransactDataResponse(
      card: AtomicTransactCardData(
        number: card.number,
        expiry: card.expiry, // MM/YY
        cvv: card.cvv,
        cardType: AtomicTransactCardType.debit,
      ),
      identity: const AtomicTransactIdentity(
        firstName: 'Ada',
        lastName: 'Lovelace',
        postalCode: '84043',
      ),
    );
  },
);

Returning null sends nothing back, and Transact keeps waiting for data.
