flutter_billing #

A plugin for Flutter that enables communication with billing API in iOS and Android.

This plugin implements in app purchases rather than Android Pay or Apple Pay. Both Apple and Google collect fees upon each successful transaction made using this plugin.

Warning: This plugin is still under development, some billing features are not available yet and testing has been limited. Feedback and Pull Requests are welcome.

Using #

Add flutter_billing flutter_billing as a dependency in pubspec.yaml.

Create an instance of the plugin:

final Billing billing = new Billing(onError: (e) {
  // optionally handle exception

Request available products for purchase:

final List<BillingProduct> products = await billing.getProducts(<String>[


final BillingProduct product = await billing.getProduct('my.product.id');
if (product != null) {
  // success
} else {
  // something went wrong

Request purchased products (each purchase is a product identifier):

final Set<String> purchases = await billing.getPurchases();

Check if a product is already purchased:

final bool purchased = purchases.contains('my.product.id');


final bool purchases = await billing.isPurchased('my.product.id');

Purchase a product:

final bool purchased = await billing.purchase(productId);
