RequireMappedAmplitudeEventTrackerFactory
object RequireMappedAmplitudeEventTrackerFactory : AmplitudeEventTrackerFactory, FallbackFactory(source)
Fails on any event that reaches it. Put it last in a chain to turn an event nobody wired up into a loud failure rather than a silent no-op.
The alternative to ending a chain with GenericAmplitudeEventTrackerFactory, which sends everything.
