Event types

Event types are automatically created in your schema when you create an event trigger.

An event trigger is a special kind of flag that has a Void return type — it doesn't return a value, but can be called like any other flag, to log an event.

By default, new event types contain:

• A context field with the Context type, so they can capture the top-level context passed to the SDK.

• A properties field with an automatically created type, e.g. PageViewEventProperties. By default, the type is empty, but you can add event-specific properties here, e.g. href. You can then pass properties as an argument when calling the event trigger from your code.

This setup enables you to log events with both the top-level context you pass to the SDK and extra event-specific properties, with full end-to-end type safety based on your schema.
