logEcommercePurchase method

Future<void> logEcommercePurchase({ String currency, double value, String transactionId, double tax, double shipping, String coupon, String location, int numberOfNights, int numberOfRooms, int numberOfPassengers, String origin, String destination, String startDate, String endDate, String travelClass, })

Logs the standard ecommerce_purchase event.

This event signifies that an item was purchased by a user. Note: This is different from the in-app purchase event, which is reported automatically for Google Play-based apps. Note: If you supply the value parameter, you must also supply the currency parameter so that revenue metrics can be computed accurately.
