                  children: <Widget>[
                    SizedBox(
                      
                      child: ListView(

                      children: [
                        Widget1(),

You should use SingleChildScrollView for the horizontal scroll and the ListView for vertical scroll. The SingleChildScrollView is the first child of the ListView and also scrolls up if you scroll the bottom widgets. Just replace List.generate... with your list of widgets:

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Material App',
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Material App Bar'),
        ),
        body: ListView(
          children: [
            SingleChildScrollView(
              scrollDirection: Axis.horizontal,
              child: Row(
                children: List.generate(2, (index) => Container(
                  child: Text("$index"),
                  width: 400,
                  height: 200,
                  alignment: Alignment.center,
                  color: Colors.blue,
                  margin: EdgeInsets.all(20),
                )),
              ),
            ),
            ...List.generate(5, (index) => Container(
              child: Text("$index"),
              width: 200,
              height: 200,
              alignment: Alignment.center,
              color: Colors.red,
              margin: EdgeInsets.all(20),
            ))
          ],
        )
      ),
    );
  }
}

Using it in the below fashion I'm able to scroll the first row horizontally and the entire Column vertically.

SizedBox(
    height: 200,
    child: SingleChildScrollView(
      child: Column(
        children: [
          SizedBox(
            height: 50,
            width: 100,
            child: ListView(
              scrollDirection: Axis.horizontal,
              children: const [
                SizedBox(
                  width: 50,
                  child:
                      Card(margin: EdgeInsets.all(5), color: Colors.blue),
                ),
                SizedBox(
                  width: 50,
                  child:
                      Card(margin: EdgeInsets.all(5), color: Colors.blue),
                ),
                SizedBox(
                  width: 50,
                  child:
                      Card(margin: EdgeInsets.all(5), color: Colors.blue),
                ),
              ],
            ),
          ),
          const SizedBox(
              height: 50,
              width: 50,
              child: Card(margin: EdgeInsets.all(5), color: Colors.blue)),
          const SizedBox(
              height: 50,
              width: 50,
              child: Card(margin: EdgeInsets.all(5), color: Colors.blue)),
          const SizedBox(
              height: 50,
              width: 50,
              child: Card(margin: EdgeInsets.all(5), color: Colors.blue)),
          const SizedBox(
              height: 50,
              width: 50,
              child: Card(margin: EdgeInsets.all(5), color: Colors.blue)),
        ],
      ),
    ),
  )

Try to play around with the number of SizedBoxes and their sizes.

In your case, the error might be because there are no constraints for the ListView dimensions.
