exposureEvent property
ExposureEvent is the event that marks a subject as enrolled — the analysis denominator — defaulting to the SDK's $feature_flag_called marker.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? exposureEvent;
