Is it possible to add buttons or text to the screen using the dropdownmenu selection to determine which buttons to display? I'm currently not getting anything displayed after the dropdowmenu. Do I need to refresh something? Thanks

  const Page2({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        theme: ThemeData(
            textTheme: TextTheme(
                displayLarge: const TextStyle(
                    fontSize: 84, fontWeight: FontWeight.bold))),
        home: Scaffold(
            body: Center(
                child: Column(children: <Widget>[
          SizedBox(height: 50),
          //children: [
          DropdownMenu(
              width: 200,
              textStyle: TextStyle(fontSize: 14),
              label: const Text('Session Options'),
              inputDecorationTheme: InputDecorationTheme(
                  isDense: true,
                  contentPadding: const EdgeInsets.symmetric(horizontal: 5),
                  constraints: BoxConstraints.tight(const Size.fromHeight(40)),
                  border: OutlineInputBorder(
                    borderRadius: BorderRadius.circular(10),
                  )),
              onSelected: (value) {
                debugPrint(value);
                if (value == 'Create Session') {
                  Set<String> searchType = {'Interior'};
                  SegmentedButton(segments:<ButtonSegment<String>>[ButtonSegment<String>(
                    value:'Interior',label: Text('Interior')),], selected: searchType,);
                }
              },
              dropdownMenuEntries: <DropdownMenuEntry<String>>[
                DropdownMenuEntry(
                    value: 'Create Session', label: 'Create Session'),
                DropdownMenuEntry(value: 'Edit Session', label: 'Edit Session'),
                DropdownMenuEntry(
                    value: 'Delete Session', label: 'Delete Session'),
              ]
            ),
          ]
        )
      )
    )
  );
  }
}```
