I’ll tell you everything you need to know about adding Flutter to a flutter app.

We will use Firebase & Flutter only.

In this course, you'll add two types of In-App Purchases to an app and verify these purchases using Firebase.

The first purchase, "Get Premium" gives users premium access. This only has to be purchased once and is available forever. Such a purchase is non-consumable because the app cannot consume it but is valid forever.

The second option, "Get Game Coin" gives the user a direct benefit of 10 Gold Coins. These are directly available to the user and can be bought many times. This is called a consumable as it is directly consumed and can be consumed multiple times.

The backend service (provided for you) verifies the purchases using Cloud Functions and Firestore. Using Firebase makes the process easier, and in your production app, you can use this backend service. It's EASY | SECURE | RECOMMEND FOR PRODUCTION APP.

Consumable (pay every-time)

A consumable In-App Purchase must be purchased every time the user downloads it. One-time services, such as fish food in a fishing app, are usually implemented as consumables.

Non-Consumable (one time payment)

Non-consumable In-App Purchases only need to be purchased once by users. Services that do not expire or decrease with use are usually implemented as non-consumables, such as new race tracks for a game app.
