logPurchase method

Future<void> logPurchase({ String? currency, String? coupon, double? value, List<AnalyticsEventItem>? items, double? tax, double? shipping, String? transactionId, String? affiliation, Map<String, Object?>? parameters, AnalyticsCallOptions? callOptions, })

Logs the standard purchase event.

This event signifies that an item(s) was purchased by a user. Note: This is different from the in-app purchase event, which is reported automatically for Google Play-based apps.
