    case AppLifecycleState.inactive: _triggerIfNotNull(inactiveCallback); _triggerIfNotNull(suspendCallback); break;
    case AppLifecycleState.paused: _triggerIfNotNull(pauseCallback); _triggerIfNotNull(suspendCallback); break;
    case AppLifecycleState.detached: _triggerIfNotNull(detachCallback); _triggerIfNotNull(suspendCallback); break;
