![]() In this part of the codelab you'll install the in_app_purchase plugin. Note that the IDs for the iOS and Android stores don't have to be identical, however keeping them identical is less error prone and therefore in this codelab we will also use identical identifiers. To do so open the adle file under android/app, and change your applicationId (on line 37 in the screenshot below) to the application ID, the same as the iOS bundle identifier. You can now close Xcode and go back to Android Studio to finish the configuration for Android. Enter the bundle identifier you've just chosen under the Team field to set your team. Double-click Runner to edit your project settings, and click Signing & Capabilities. In Xcode's folder structure, the Runner project is at the top, and the Flutter, Runner, and Products targets are beneath the Runner project. With the project open in Android Studio, right-click the iOS folder, click Flutter, and open the module in the Xcode app. Think of an identifier for your app, you are now going to set that in the project settings.įirst, set up the bundle identifier for iOS. For example when making an in app purchase app for v we would use. These identifiers are usually made using a reverse domain name notation. For the iOS App Store this is called the bundle identifier and for the Android Play Store this is the application ID. The apps you are going to make need to communicate with the App Store and Play Store to know which products are available and for what price. ![]() With either editor, ensure that the latest Dart and Flutter plugins are installed. We used Android Studio for the screenshots, but Visual Studio Code is also a great option. Open the starter project from step_00 in your favorite IDE. The code of the last step is under the folder complete. If you want to skip forward or see what something should look like after a step, look in the directory named after the step you are interested in. The starter code is in step 0, so locating the matching files is as easy as: cd flutter-codelabs/in_app_purchases/step_00 The directory structure under flutter-codelabs/in_app_purchases contains a series of snapshots of where you should be at the end of each named step. The code for this codelab is in flutter-codelabs/in_app_purchases. The sample code is cloned into a flutter-codelabs directory that contains the code for a collection of codelabs. Or, if you have GitHub's cli tool installed, use the following command: gh repo clone flutter/codelabs flutter-codelabs To clone the GitHub repository from the command line, use the following command: git clone flutter-codelabs To start this codelab, download the code and change the bundle identifier for iOS and the package name for Android. Xcode 12 or later (for iOS development).How to communicate with the stores to verify purchases and store them in Firestore.How to configure the App Store and Play Store with purchasable products.You will also extend a Dart backend app to verify and store the purchased items.You will extend an app to support consumable purchases and subscriptions.Firestore is used to make the process easier, but in your production app, you can use any type of backend service. The backend service (also provided for you) runs as a Dart app, verifies that the purchases are made, and stores them using Firestore. While the subscription is active the user will get Dashes more quickly, but when he stops paying for the subscription the benefits also go away. The third and last purchase option is a subscription. Such a purchase is called non-consumable because it cannot be consumed by the app but is valid forever. This only has to be purchased once and is available forever. The second option upgrades the Dash to a more beautiful Dash. This is called a consumable as it is directly consumed and can be consumed multiple times. These are directly available to the user and can be bought many times. The first purchase option gives the user a direct benefit of 2000 Dashes. A subscription that doubles the automatically generated clicks. ![]() A one-time upgrade purchase to make the old style Dash into a modern style Dash.A repeatable purchase option for 2000 Dashes at once.You will add the following purchase options: The provided app, Dash Clicker, contains a game that uses the Dash mascot as currency. In this codelab you'll add three types of in-app purchases to an app (provided for you), and verify these purchases using a Dart backend with Firebase. Adding in-app purchases to a Flutter app requires correctly setting up the App and Play stores, verifying the purchase, and granting the necessary permissions, such as subscription perks. ![]()
