Amazon Appstore IAP Sample in Flutter

This project is a sample Flutter App to showcase how you can use Amazon Appstore IAP in your Flutter project using the plugin from Dooboolab

Prerequisites

To run the app an test it with the Amazon Appstore, you will need the following:

• Flutter SDK installed
• Your favourite IDE
• An Amazon Appstore developer account
• An Amazon Fire device

✅ Features

The project is about a fictional music app GIOLAQ Music ( Note: I'm not an actual singer 👨‍🎤 )

What you can purchase:

• The right to play the whole album of GIOLAQ
• The yearly subscription to all the music produced by GIOLAQ
• Tickets granting you access to GIOLAQ live music concerts (one ticket per concert)

These three in-app purchases correspond respectively to the three types of IAP supported by the Amazon Appstore:

• Consumables: Purchase that is made, then consumed within the app, such as extra lives, extra moves, or in-game currency. May be purchased multiple times.
• Entitlements: One-time purchase to unlock access to features or content within an app or game.
• Subscriptions: Offers access to a premium set of content or features for a limited period of time.

Note: Make sure to review our docs on IAP for Amazon Appstore.

Head to purchase page to purchase one of the three different IAP items:

• Music Album
• Yearly subscription
• Ticket

Music Album and Yearly subscription will unlock the music in the music screen.

Ticket will increase the ticket counter in the music screen You can consume the ticket tapping on the ticket icon
