Horizontal listview not scrolling on web but scrolling on mobile

Question

After flutter 2.5 update listview is scrolling only on mobile platforms. It doesn't scroll when I open it on the web. It was working fine in the previous version. I tried the scroll physics but it didn't work. what do you suggest i do? sorry for my bad english.

          return SizedBox(
            height: 400,
            child: ListView.builder(
                physics: ClampingScrollPhysics(),
                scrollDirection: Axis.horizontal,
                // ignore: unnecessary_null_comparison
                itemCount: items == null ? 0 : items.length,
                itemBuilder: (context, index) {
                  return GestureDetector(
                      onTap: () {
                        LoginForm();
                      },
                      child: Container(
                        margin:
                            EdgeInsets.symmetric(horizontal: 20, vertical: 6),
                        child: SizedBox(
                          width: 400,
                          height: 50,
                          child: Stack(
                            fit: StackFit.expand,
                            children: <Widget>[

Flutter 2.5 Summary

ScrollBehaviors now allow or disallow drag scrolling from specified PointerDeviceKinds. ScrollBehavior.dragDevices, by default, allows scrolling widgets to be dragged by all PointerDeviceKinds except for PointerDeviceKind.mouse.

import 'package:flutter/material.dart';

// Set ScrollBehavior for an entire application.
MaterialApp(
  scrollBehavior: MyCustomScrollBehavior(),
  // ...
);

import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';

class MyCustomScrollBehavior extends MaterialScrollBehavior {
  // Override behavior methods and getters like dragDevices
  @override
  Set<PointerDeviceKind> get dragDevices => {
        PointerDeviceKind.touch,
        PointerDeviceKind.mouse,
      };
}
