_themeMode = _settingsService.themeMode();
// _cardinalitySelection = await _settingsService.cardinalitySelection();
_cardinalitySelection = CardinalitySelection(
_sharedPreferences.getBool("cardinality.singularEnabled") ?? true,
_sharedPreferences.getBool("cardinality.pluralEnabled") ?? true);
// Important! Inform listeners a change has occurred.
