final String title;
[@override](/user/override)
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
int _currentIndex = 0; // 当前选中的步骤索引
[@override](/user/override)
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: SimpleStepperFlutter(
children: const [

),
floatingActionButton: FloatingActionButton(
onPressed: () {
setState(() {
if (_currentIndex < 4) {
_currentIndex++;
} else if (_currentIndex == 4) {
