Dart SDK

Availability

Supports Dart from 2.0 to above

How to install

Add the following line in dependencies in your pubspec.yaml file and save it:

dependencies:
  nps_sdk: "^1.0.0"

If pub get wasn't automatically ejecuted, you can do it manually by opening a terminal in your project and executing the command:

pub get

Now you are ready to import our SDK:

import 'package:nps_sdk/nps_sdk.dart';

Configuration

It's a basic configuration of the SDK

import 'dart:async';

import 'package:nps_sdk/nps_sdk.dart';

main(List<String> arguments) async {
  Nps nps = new Nps(sandbox);
}

Here is an simple example request:

import 'dart:async';

import 'package:nps_sdk/nps_sdk.dart';

main(List<String> arguments) async {
  Nps nps = new Nps(sandbox);

  Map createPaymentMethodTokenParams = {
    "psp_Version": "2.2",
    "psp_MerchantId": "sdk_test",
    "psp_CardInputDetails": {
      "Number": "4507990000000010",
      "ExpirationDate": "2501",
      "SecurityCode": "123",
      "HolderName": "JOHN DOE"
    },
    "psp_ClientSession": "YOUR_CLIENT_SESSION_HERE"
  };

  Future response = nps.createPaymentMethodToken(nps, createPaymentMethodTokenParams);
  response.then((resp) {
            print(resp["psp_ResponseCod"]); //Only one key
            jsonPrettyPrint(resp); //All the XML
          })
          .catchError((error) => print);
}

Environments

import 'package:nps_sdk/nps_sdk.dart';

Nps nps = new Nps(sandbox);
Nps nps = new Nps(staging);
Nps nps = new Nps(production);

Error handling

With this SDK you will be able to handle errors as you prefer. In order to do this, you just need to specify what you want to do with the error in the catchError callback:

import 'dart:async';

import 'package:nps_sdk/nps_sdk.dart';

main(List<String> arguments) async {
    //Code
    
    Future response = nps.createPaymentMethodToken(nps, createPaymentMethodTokenParams);
      response.then((resp) => print(resp["psp_ResponseCod"]))
              .catchError((error) {
                //Your code to handle the error
              });
}
