trackRevenue method

@override Future<void> trackRevenue({ required double amount, required String currency, Map<String, dynamic>? properties, })

Tracks a revenue-generating event.

This is a convenience method that wraps trackEvent with specialized revenue properties (revenue and currency).

Parameters:

• amount: The decimal value of the transaction.
• currency: The 3-letter ISO code (e.g., "USD").
• properties: Optional additional context.

Implementation

@override
Future<void> trackRevenue({
  required double amount,
  required String currency,
  Map<String, dynamic>? properties,
}) async {
  if (amount < 0) {
    throw InvalidEventDataError('Revenue amount must be non-negative');
  }

  final eventProperties = Map<String, dynamic>.from(properties ?? {});
  eventProperties['revenue'] = amount;
  eventProperties['currency'] = currency;

  await trackEvent('revenue', eventProperties);
}
