herald_amplitude 1.0.0-dev.1

A Herald vendor adapter that sends to Amplitude: events, user properties, screen views and revenue.

Herald for Amplitude

Sends Herald events and properties to Amplitude, over amplitude_flutter: events, user properties, screen views and revenue.

final amplitude = Amplitude(
  Configuration(
    apiKey: apiKey,
    optOut: true, // silent until consent
    autocapture: const AutocaptureOptions(screenViews: false), // Herald sends screen views
  ),
);
final tracker = AmplitudeAnalyticsTrackerService(
  eventTrackerFactory: CompositeAmplitudeEventTrackerFactory([
    ScreenViewAmplitudeEventTrackerFactory(amplitude),
    GenericAmplitudeEventTrackerFactory(amplitude),
  ]),
  propertySetterFactory: CompositeAmplitudePropertySetterFactory([
    GenericAmplitudePropertySetterFactory(amplitude),
  ]),
);
final service = AmplitudeAnalyticsService(amplitude);

Values keep their types. A ScreenViewEvent becomes [Amplitude] Screen Viewed, and purchases go through AmplitudeRevenueEvent and RevenueAmplitudeEventTracker, deduplicated by insertId. Amplitude forgets the opt-out between launches, so re-apply the stored answer after start().
