Use case

Currently, AdaptiveScaffold takes only List<NavigationDestination> as destinations parameter, which is understandable, to make its type common. But, it results in us not being able to use other parameter exposed by NavigationRailDestination such as individual indicatorColor, indicatorShape and the most important one for me personally, padding.

Proposal

Expose a mapper method parameter to allow us customize individual NavigationRailDestination.

    return AdaptiveScaffold(
      mapNavigationRailDestination: (int index, NavigationDestination dest) {
        return NavigationRailDestination(
          icon: dest.icon,
          label: Text(dest.label),
          padding: newSections.contains(index)
              ? const EdgeInsets.only(top: 12)
              : EdgeInsets.zero,
        );
      },
    );
