SliverList是一个包含盒子小部件的条子。是否有包含条子小部件的条子？

我试图嵌套 flutter_sticky_headers 来创建时间线，但SliverStickyHeader只接受单个条子作为参数（请参阅 中的注释monthSlivers()）。

class HomeView extends StatelessWidget {
  final HomeViewModel viewModel;

  HomeView(this.viewModel);

  List<Widget> entryTiles(List<EntryTileViewModel> entryVMs) {
    return entryVMs.map((entryVM) => EntryTile(viewModel: entryVM)).toList();
  }

  List<Widget> daySlivers(List<DaySection> daySections) {

        header: DayHeader(
          viewModel: DayHeaderViewModel(date: daySection.date),
        ),
        sliver: SliverList(
          delegate: SliverChildBuilderDelegate(
                (context, i) => entries[i],
            childCount: entries.length,
          ),
        ),
      );
    }).toList();
  }

  List<Widget> monthSlivers() {
    return viewModel.monthSections.map((monthSection) {
      var days = daySlivers(monthSection.daySections);
      return SliverStickyHeader(
        header: MonthHeader(
          viewModel: …
