SliverList inside ExpansionTile without Shrinkwrap (Flutter)

Question

Is there any way to build a SliverList inside ExpansionTile? The reason I want to do this, I have a really large amount of data that needs to be put inside the expansion tile. Expansion tile needs List but SliverList should be inside CustomScrollView. If I use custom Scroll View inside Expansion tile's Children and put SliverList in it renders nothing. If I set Shrinkwrap true to CustomScrollView it renders Every Widget at a time. So, How can it be fixed?

Here is an example,

class Expamle extends StatelessWidget {
  const Expamle({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return CustomScrollView(
      slivers: [
        ....,
        SliverList(
          delegate: SliverChildBuilderDelegate(
            (_, i) => ExpansionTile(
              title: const Text('Title'),
              children: [
                // But it is Illegal here
                SliverList(
                  delegate: SliverChildBuilderDelegate(
                    (_, i) => const Text('Child'),
                    childCount: 10,
                  ),
                ),
                // It does not render anything
                CustomScrollView(
                  slivers: [
                    SliverList(
                      delegate: SliverChildBuilderDelegate(
                        (_, i) => const Text('Child'),
                        childCount: 10,
                      ),
                    ),
                  ],
                ),
                // It Works but render all widgets at a time
                CustomScrollView(
                  shrinkWrap: true,
                  slivers: [
                    SliverList(
                      delegate: SliverChildBuilderDelegate(
                        (_, i) => const Text('Child'),
                        childCount: 10,
                      ),
                    ),
                  ],
                ),
              ],
            ),
          ),
        ),
      ],
    );
  }
}

Definitely not a proper solution but just a rought workaround. I need the same functionality and it seems it can't be achieved with Flutter currently. So I ended up changing the design a bit. Instead of having a full list of data in your expansion tile, you can just show a preview of some small number of items which can be rendered at once safely. Then, at the end of this short list, add a "Show all (number)" button which will show the full data in a separate screen or dialog.
