使用 CustomScrollView，我對您的代碼進行了一些重構 import sliver_tools package for sliverStack
import 'package:sliver_tools/sliver_tools.dart';
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
@override
// ignore: library_private_types_in_public_api
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: CustomScrollView(
physics: const AlwaysScrollableScrollPhysics(),

const SliverAppBar(
