super_easy_in_app_purchase

A flutter plugin for creating in app purchase in a super simple way.

In App Purchase(IAP) is a very complicated thing to implement in any mobile app for many years. Generally, it takes about 200 lines of code(in flutter) just to implement IAP. But I have tried my best to make it as simple as possible using this plugin.

How to use

Step 1:

First add this package in your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  super_easy_in_app_purchase: any

Make sure to GET all the pub packages after saving this file.

Step 2:

Android

Add the INTERNET permission in your AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET" />

Step 3

Create in app product in your google play account and app store account. Follow the links for more detail steps: Creating In App Product in Google Play Store Creating In App Product in Apple App Store

Step 4

In your main() function in main.dart file, import the package and add the static method, start():

import 'package:super_easy_in_app_purchase/super_easy_in_app_purchase.dart';
void main() {
  SuperEasyInAppPurchase.start();
  runApp(MyApp());
}

Step 5

Finally, use the package

Create a class level variable in your State class of any stateful widget

Also make sure to import the library package in your dart file.

class _MyAppState extends State<MyApp> {
  SuperEasyInAppPurchase inAppPurchase;
  ...

Initialise that variable in initState() method

This is the most important and difficult step to understand.

@override
void initState() {
  super.initState();
  inAppPurchase = SuperEasyInAppPurchase(
    // Any of these function will run when its corresponding product gets purchased successfully
    // For simplicity, I have just printed a message to console
    whenSuccessfullyPurchased: <String, Function>{
      'product1': () async => print('Product 1 purchased!'),
      'product2': () async => print('product 2 activated!'),
    },

    // Any of these function will run when its corresponding product gets refunded
    // For simplicity, I have just printed a message to console
    // This is completely an optional
    whenUpgradeDisabled: <String, Function>{
      'product1': () async => print('Product 1 refunded !'),
      'product2': () async => print('product 2 refunded !'),
    },
  );
}

SuperEasyInAppPurchase() constructor takes two parameters, first one is whenSuccessfullyPurchased, it takes a Map<String, Function> each pair in the map represents a Product ID (String) and its function which will executed after successfull purchase.

The second optional parameter whenUpgradeDisabled also takes Map<String, Function> but this time, these functions will get executed when one of your product is refunded. So these functions main task is to disable the corresponding product.

Start a purchase

Write this line of code in your button's onPressed listener:

await inAppPurchase.startPurchase('myProductID');

or if your product is consumable, then use:

await inAppPurchase.startPurchase('myProductID', isConsumable: true);

Note: Consumables are those products which needs to be purchased again and again, like - The fuel of racing car. By default, isConsumable parameter is set to false.

Consume(remove) the purchase

In order to remove the purchase, use:

await inAppPurchase.consumePurchase('myProductID');

When you consume a purchase, the user has to purchase it again in order to use its features.
