Card-Flutter #
Integrating Flutter Card SDK in your application
Introduction #
Before diving into the development process, it's essential to establish the prerequisites and criteria necessary for a successful build. In this step, we'll outline the specific iOS/Android requirements, including the minimum SDK version and other important details you need to consider. Let's ensure your project is set up for success from the very beginning.
Sample Demo #
Step 1: Requirements #
- We support from iOS 13.0+
- Dart 3.0.0+
- Java version 11
- A minimum Android SDK/API level of 24
- In order to be able to use card scanner functionality, please make sure you added the correct permission key-value in the iOS project info.plist.
<key>NSCameraUsageDescription</key> <string>Card SDK needs it for scanner functionality</string>
- in order to accept online payments on your application, you will need to add at least the Internet permission in the manifest file.
<uses-permission android:name="android.permission.INTERNET" /> //get internet access to complete online payments
Step 2: Get Your Public Keys #
While you can certainly use the sandbox keys available within our sample app which you can get by following the installation process, however, we highly recommend visiting our onboarding page, there you'll have the opportunity to register your package name and acquire your essential Tap Key for activating Card-Flutter integration. If you will support both iOS and Android, you will need to have two different keys for each app.
Step 3: Installation #
In the pubspec.yaml
of your flutter project, add the following dependency:
dependencies:
card_flutter: 1.0.8
In your library add the following import:
import 'package:card_flutter/card_flutter.dart';
Step 4: Integrating Card-Flutter #
This integration offers two distinct options: a simple integration designed for rapid development and streamlined merchant requirements, and an advanced integration that adds extra features for a more dynamic payment integration experience.
Integration Flow #
Noting that in Flutter, you will use our card form like any other widget. While creating, the widget you will also need to pass the parameters & listen to the callbacks based on your needs.
- You will have to create a variable of type TapCardViewWidget
- While intialising the widget:
- Pass the parameters to the widget.
- Implement the provided interfaces/callbacks
- Our card widget is a stateful one, depends on stateful variable to generate the token. More to follow.
- Start tokenizing a card on demand.
Using Code to create the TapCardViewWidget #
- Creating the TapCardViewWidget from code
- Head to your controller where you want to display the
TapCardViewWidget
as a widget. - Import
Card-Flutter
as followsimport 'package:card_flutter/models/models.dart
. - In the coming code sample, we will show how to embed the card form within your widget tree.
TapCardViewWidget( sdkConfiguration: const {}, generateToken: false // More on this later),
Simple Integration #
Here, you'll discover a comprehensive table featuring the parameters applicable to the simple integration. Additionally, you'll explore the various methods for integrating the SDK. Furthermore, you'll gain insights into card tokenization after the initial payment and learn how to receive the callback notifications.
Parameters #
Each parameter is linked to the reference section, which provides a more in depth explanation of it.
|Parameter|Description | Required | Type| Sample
|--|--|--| --|--| | operator| Key obtained after registering your package name, also known as Public key. | True | Map| {"operator": {"publicKey": "pk_test_YhUjg9PNT8oDlKJ1aE2fMRz7"}
| | scope| Defines the intention of using Card-Flutter. | True | String| String scope = "Token"
| | purpose| Defines the intention of using the generated Token. | True | String| String purpose = "Charge"
| | order| Order details linked to the token. | True | Map
| order = {"id":"", "amount":1, "currency":"SAR", "description": "Authentication description", "reference":""}
| | customer|Customer details for tokenization process. | True | Map
| customer = {"id":"", "name":[{"lang":"en","first":"TAP","middle":"","last":"PAYMENTS"}], "nameOnCard":"TAP PAYMENTS", "editble":true, "contact":{"email":"tap@tap.company", "phone":{"countryCode":"+965","number":"88888888"}}}
|
Configuring the Card-Flutter SDK #
While creating the widget as previously mentioned, it is time to pass the parameters needed for the SDK to work as expected and serve your need correctly.
- Creating the parameters
To allow flexibility and to ease the integration, your application will only has to pass the parameters as aDictionary[String:Any]
.
First, let us create the required parameters:
/// The minimum needed configuration Map<String,dynamic> parameters = {
"customer":{ "name":[ { "first":"TAP", "middle":"", "lang":"en", "last":"PAYMENTS" } ], "contact":{ "email":"tap@tap.company", "phone":{ "countryCode":"+965", "number":"88888888" } } }, "purpose":"Charge", "operator":{ "publicKey":"pk_test_YhUjg9PNT8oDlKJ1aE2fMRz7" }, "scope":"Token", "order":{ "description":"", "currency":"SAR", "amount":1.0 }}
- Pass these parameters to the TapCardViewWidget widget
// We provide the card view the needed parameters. TapCardViewWidget(sdkConfiguration: parameters, generateToken: generateToken,) // This generate token is a stateful variable, if set to true token will be generated

Tokenise the card #
📘
A token is like a secret code that stands in for sensitive info, like credit card data. Instead of keeping the actual card info, we use this code. Tokens are hard for anyone to understand if they try to peek, making it a safer way to handle sensitive stuff.
Following the above code samples, once the TapCardViewWidget now has a valid input, you will be able to start the tokenization process by changing the stateful variable generateToken
to true as we declared above, which you can find by following Step 5 - Tokenize the card.
Advanced Integration #
The advanced configuration for the Card-Flutter integration not only has all the features available in the simple integration but also introduces new capabilities, providing merchants with maximum flexibility. You can find a code below, where you'll discover comprehensive guidance on implementing the advanced flow as well as a complete description of each parameter.

Receiving Callback Notifications (Advanced Version) #
The below will allow the integrators to get notified from events fired from the TapCardViewWidget.
TapCardViewWidget(
sdkConfiguration: widget.dictionaryMap,
onReady: () {
},
onFocus: () {
},
onSuccess: (String? success) {
},
onValidInput: (String? validInput) {
},
onHeightChange: (String? heightChange) {
},
onBinIdentification: (String? bindIdentification) {
},
onChangeSaveCard: (String? saveCard) {
},
onError: (String? error) {
},
generateToken: true,
cardNumber: "51234500********",
cardExpiry: "01/39", ),
Step 5: Tokenize the Card #
The Card-Flutter SDK provides a stateful variable, that allows you to instruct it to start the tokenization process on demand or whenever you see convenient, in your logic flow. As a guidance we would only recommend calling this interface after getting onValidInput with data true
callback as described above and shown in the code block below.
📘
Tokenize the Card
> #
What is a Token?
A token is like a secret code that stands in for sensitive info, like credit card data. Instead of keeping the actual card info, we use this code. Tokens are hard for anyone to understand if they try to peek, making it a safer way to handle sensitive stuff.
> #
What is Tokenization of a Card?
Card tokenization is like changing your credit card into a secret code. You can use this code safely without showing your actual card info. It's a common practice in payments to keep things secure and prevent your card details from being seen by others.
> #
Why Do I Need to Tokenize a Card?
There are several reasons to tokenize a card:
- Security > Tokenization helps protect sensitive card data, reducing the risk of data breaches or unauthorized access.
- Compliance > Many regulations and industry standards, like PCI DSS, require the use of tokenization to safeguard cardholder data.
- Recurring Payments > Tokens are useful for recurring payments, as they allow you to charge a customer's card without storing their actual card details.
- Convenience > Tokens simplify payment processing, as you only need to deal with tokens instead of card numbers.
- Declare a boolean variable in your stateful widget
- This variable will be passed to the TapCardViewWidget while initialisation as below.
- Whenever you need, change it to true to trigger the tokenization status in the TapcardViewWidget.
👍
Also, once you correctly trigger the interface, you should expect to hear back from the SDK in one of two callbacks, onSuccess or onError.
