Flutter FawryPay

Explain

This plugin is for FawryPay. It's implemented the native SDKs of Mobile, and Web to work on Flutter environment.

It works for Android fine. iOS works fine on Real Device only (FawryPay Requirements).

Contribution: Eng. Ahmed Mahmoud

Getting Started

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_fawry_pay: ^0.0.6

Android

You have to edit AndroidManifest.xml file with following.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" />
    <application
        tools:replace="android:theme,android:label,android:name">
    </appliaction>
</manifest>

And download this file, and put it in app/libs folder (If not exist, create it).

In Release Mode

Please add these two lines in app/gradle

buildTypes {
    release {
        // ....
        shrinkResources false
        minifyEnabled false
    }
}

iOS

No actions needed, just work on Real Device only. Need xCode 12.x and SWIFT 5.3.x.

Web

No actions needed, just go ahead.

Usage

You just have to import the package with

import 'package:flutter_fawry_pay/flutter_fawry_pay.dart';

Then, you need to initialize the SDK.

FlutterFawryPay.instance.init(
    // Set the merchant ID here for one time only.
    merchantID: Keys.merchantID,
    style: Style.STYLE1,
    // If set to true, you must set username and email.
    skipCustomerInput: true,
    // Must be a phone number.
    username: "01234567890",
    email: "abc@test.com",
    // For web how you show the Fawry screen.
    webDisplayMode: DisplayMode.SIDE_PAGE,
    // You should set environment here.
    environment: Environment.TEST, 
);

And when you are ready for production you have to set the environment to LIVE.

Now, you can stream the result data that from SDK.

FlutterFawryPay.instance.callbackResultStream().listen((event) {
  FawryResponse response = FawryResponse.fromMap(data);
  print(response);
});

Let's now make our first payment initialize, you must set your merchantID that token from FawryPay system, and set your FawryItems that the user will pay for.

Note that: there's error in native FawryPay SDK for Android and iOS to retrieve again customParam.

FlutterFawryPay.instance.initialize(
    returnUrl: "test.com", // For Web use only.
    items: [
    FawryItem(sku: "1", description: "Item 1", qty: 1, price: 20.0),
    ],
    customParam: {
    "order_id": "123213",
    "price": 231.0,
    },
);

You can set some parameters like: merchantRefNumber, customParam.

So now, it was initialized well, how to start payment? You have TWO ways.

First way: Native Fawry Button

You can use the native button for FawryPay SDK. through this only widget.

FawryButton()

Second way: Your custom widget

You can use your own widget with a function to call with FlutterFawryPay.instance.startProcess().

RaisedButton(
  onPressed: () async {
  FawryResponse response = await FlutterFawryPay.instance.startProcess();
  },
  child: Text("Start Payment"),
)

There's a function in FawryPay is CardTokenizer (Android & iOS only, not for Web), you can use it like this way:

Note that: there's error in native FawryPay SDK for android to retrieve again customParam.

FlutterFawryPay.instance.initializeCardTokenizer(
  customerMobile: "01234567890",
  customerEmail: "abc@test.com",
  customParam: {
    "order_id": "123213",
    "price": 231.0,
  },
);

Last function you can use is reset the initialization (Android & Web only), doing that:

FlutterFawryPay.instance.reset();
