onError property

void Function(BuildContext context, ErrorEvent error)? onError

Called when the web app emits an Event.ERROR.

When provided, the integrator owns the error UI and the SDK's default navigation to its generic error page is suppressed. Regardless of this callback, the ErrorEvent is always published on the onErrorEvent stream, so a stream subscription observes errors but does NOT suppress the default navigation — use this callback for that.

Implementation

void Function(BuildContext context, ErrorEvent error)? onError;
