Is there a cleaner way to do this? That is, use an optional route as an argument injected into

GoRoute(
  path: 'results',
  pageBuilder: (context, state) {
    final data = Provider.of<ResultsRouteData>(context);
    return SessionResultsScreen(data: data, levelUp: false);
  }
),

GoRoute(
  path: 'results/:levelUp',
  pageBuilder: (context, state) {
    final data = Provider.of<ResultsRouteData>(context);
    return SessionResultsScreen(data: data, levelUp: true);
  }
),
