如何在Flutter中关闭对话框时重定向到特定路由

showDialog(
  context: context,
  builder: (BuildContext context) {
    return AlertDialog(
      title: Text('对话框标题'),
      content: Text('对话框内容'),
      actions: <Widget>[
        FlatButton(
          child: Text('关闭'),
          onPressed: () {
            Navigator.of(context).pop(); // 关闭对话框
            Navigator.pushReplacementNamed(context, '/your_route_name'); // 重定向到特定路由
          },
        ),
      ],
    );
  },
);

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      initialRoute: '/',
      routes: {
        '/': (context) => HomePage(), // 设置主页路由
        '/your_route_name': (context) => YourPage(), // 设置特定路由
      },
    );
  }
}
