FlutterStoreKit Library

FlutterStoreKit is a Flutter library that provides functionality for managing in-app purchases and subscriptions. This documentation outlines how to use the FlutterStoreKit library in your Flutter app.

1. Initialize the Store

void main() {
  StoreKit.instance.initialize([
    'subscription_id1',
    'subscription_id2',
    'subscription_id3',
  ]);
}

2. Add Listeners

Add Pro Status Changed Listener Add a listener for pro status changes:

void _onProStatusChanged() {
  // Update UI based on purchase status
}

StoreKit.instance.addProStatusChangedListener(_onProStatusChanged);

Remove Pro Status Changed Listener Remove a listener for pro status changes:

StoreKit.instance.removeProStatusChangedListener(_onProStatusChanged);

Add Error Listener Add a listener for errors:

void _onError(String error) {
  // Handle error
  print("Error: $error");
}

StoreKit.instance.addErrorListener(_onError);

Remove Error Listener Remove a listener for errors:

StoreKit.instance.removeErrorListener(_onError);

3. Purchases

bool purchased = StoreKit.instance.isProductPurchased('product_id');
