How to give shadow to ExpansionPanelRadio widget?

I'm using ExpansionPanelList.radio to show a bunch of FAQs on the screen. As the children property only accepts a List of ExpansionPanel widgets, I can't give shadow to the ExpansionPanelRadio widget. Is there any method to give it a shadow like so:

Here's the code:

class FaqsScreen extends StatelessWidget {
  FaqsScreen({super.key});

  final List<int> _faqData = List.generate(5, (index) => index);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: SingleChildScrollView(
          child: Padding(
            padding: EdgeInsets.symmetric(horizontal: 16),
            child: ExpansionPanelList.radio(
              elevation: 0,
              expandedHeaderPadding: EdgeInsets.zero,
              children: _faqData
                  .map(
                    (faq) => ExpansionPanelRadio(
                      value: _faqData.indexOf(faq),
                      canTapOnHeader: true,
                      headerBuilder: (context, isExpanded) => ListTile(
                        contentPadding: EdgeInsets.zero,
                        title: Text('1. Lorem Ipsum is simply dummy text?'),
                      ),
                      body: Column(
                        children: [
                          Divider(),
                          Text(
                            'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry\'s standard dummy text ever since the 1500s.',
                          ),
                        ],
                      ),
                    ),
                  )
                  .toList(),
            ),
          ),
        ),
      ),
    );
  }
}

You can use ExpansionTile instead of ExpansionPanelRadio

Here is the output

and here is the sample code :

 class FaqsScreen extends StatefulWidget {
  FaqsScreen({super.key});

  @override
  State<FaqsScreen> createState() => _FaqsScreenState();
}

class _FaqsScreenState extends State<FaqsScreen> {
  final List<int> _faqData = List.generate(5, (index) => index);

  int _expandedIndex = -1; // all tiles close at beginning

  void _handleExpansion(int index) {
    setState(() {
      if (_expandedIndex == index) {
        _expandedIndex = -1; // if the same tile, then close it
      } else {
        _expandedIndex = index;
      }
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: SingleChildScrollView(
          child: Padding(
            padding: EdgeInsets.symmetric(horizontal: 16),
            child: Column(
              children: _faqData
                  .map(
                    (faq) => Container(
                      margin: EdgeInsets.all(4),
                      decoration: BoxDecoration(
                        borderRadius: BorderRadius.circular(8),
                        color: Colors.white,
                        boxShadow: [
                          BoxShadow(
                              color: Colors.black.withOpacity(0.3),
                              blurRadius: 10),
                          BoxShadow(
                            color: Colors.black.withOpacity(0.3),
                            spreadRadius: -2,
                            blurRadius: 5,
                          ),
                        ],
                      ),
                      child: ExpansionTile(
                        key: UniqueKey(),
                        onExpansionChanged: (expanded) {
                          _handleExpansion(faq);
                        },
                        initiallyExpanded: _expandedIndex == faq,
                        controller: ExpansionTileController(),
                        title: Text('1. Lorem Ipsum is simply dummy text?'),
                        children: [
                          Divider(),
                          Padding(
                            padding: const EdgeInsets.symmetric(
                                horizontal: 12.0, vertical: 8),
                            child: Text(
                              'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry\'s standard dummy text ever since the 1500s.',
                            ),
                          ),
                        ],
                      ),
                    ),
                  )
                  .toList(),
            ),
          ),
        ),
      ),
    );
  }
