onEvent method Null safety

void onEvent(
  1. SettingsAppearanceEvent event
)
override

Called whenever an event is added to the Bloc. A great spot to add logging/analytics at the individual Bloc level.

Note: super.onEvent should always be called first.

@override
void onEvent(Event event) {
  // Always call super.onEvent with the current event
  super.onEvent(event);

  // Custom onEvent logic goes here
}

Implementation

@override
void onEvent(SettingsAppearanceEvent event) {
  event.mapOrNull(
      setThemeMode: (_) => _analyticService?.trackEvent("set_theme_mode"));
  super.onEvent(event);
}
