track method

@override Future<RawEvent?> track(TrackEvent event)

Tracks an event by sending it to AppsFlyer

Takes an event object containing properties and maps them to AppsFlyer's format. Extracts revenue, currency, quantity, price and order ID into AppsFlyer's standard parameters. Removes the original properties after extraction to avoid duplication. Finally logs the event to AppsFlyer with the transformed properties.
