      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(
        title: '文件上传Demo',
      ),

}

class MyHomePage extends StatefulWidget {
  const MyHomePage({
    super.key,
    required this.title,
  });

  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(
          widget.title,

            fontSize: 16,
          ),

        padding: EdgeInsets.symmetric(
          horizontal: 15.0,
        ),
        child: Column(
          children: [
            // 示例卡片小部件
            CardWidget(
              elevation: 5,
              child: Center(
                child: Text(
                  "Card Example",
                ),
