Welcome to Ezetap Payments Flutter SDK integration! You can easily collect payments from your existing android applications by integrating the SDK.

How integration works

  1. Include the SDK in your mobile application to collect payments.
  2. SDK interfaces with a Service App, this App will be installed during run-time.
  3. Service App interfaces with the Card Device and Ezetap Servers to finish payment processing and notifies the status to SDK.

Prerequisites

Supported on Android API version 21 or above.

Use this package as a library

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get)

dependencies:
  ezetap_sdk: ^0.2.0

Import it

Now in your Dart code, you can use:

import 'package:ezetap_sdk/ezetap_sdk.dart';
