I have this flutter home.dart. The thing is that I can't scroll to down or up with the same home.dart. I want to make it scrollable. Here is the code. The first widget is working with scrolling but the last two aren't. Please help me. I have tried looking for the solution but all in vain.

import 'package:flutter/material.dart';
import 'package:nyimboo_app/screens/auth/unlogged_nav.dart';


class HomePage extends StatefulWidget {
  const HomePage({ Key? key }) : super(key: key);

  @override
  State<HomePage> createState() => _HomePageState();
}

List toolsn = [
"Yesai", "Vlog", "Laka", "Vlog" , "Vlog"


];

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {

     Widget horizontalList1 = new Container(
      margin: EdgeInsets.symmetric(vertical: 20.0),
      height: 200.0,
      child: new ListView(
      scrollDirection: Axis.horizontal,
      children: <Widget>[
        Container(width: 150.0, color: Colors.red,),
        SizedBox(width: 5.0,),
         Container(width: 150.0, color: Colors.black,),
         SizedBox(width: 5.0,),
         Container(width: 150.0, color: Colors.teal,),
         SizedBox(width: 5.0,),
         Container(width: 150.0, color: Colors.black,),
         SizedBox(width: 5.0,),


       
       
      ],
    )
    );

Where it is not clear, you can ask me please. Thank you

Add physics: NeverScrollableScrollPhysics() to ListView.builderoptions

// the scaffold body
    final makeLessonBody =  ListView.builder(
          scrollDirection: Axis.vertical,
          shrinkWrap: true,
          itemCount: toolsn.length,
          physics: NeverScrollableScrollPhysics(),
          itemBuilder: (BuildContext context, int index) {

            return makeLessonCard(toolsn[index]);

          },
    );

i think it caused by multiple ListView. then the scrollcontroller not working. in my case i usually add properties physics for the children,

body:
  Padding(
    padding: EdgeInsets.all(0.0),
    child: ListView(  // parent widget
            shrinkWrap: true,
            scrollDirection: Axis.vertical,
            children: <Widget>[

            ...... other widget is here
]

and for the children , add ClampingScrollPhysics() : Creates scroll physics that prevent the scroll offset from exceeding the bounds of the content.

final makeLessonBody =  Container(
      child: ListView.builder(
        physics: const ClampingScrollPhysics(),
        scrollDirection: Axis.vertical,
        shrinkWrap: true,

Widget horizontalList1 = new Container(
      margin: EdgeInsets.symmetric(vertical: 20.0),
      height: 200.0,
      child: new ListView(
      physics: const ClampingScrollPhysics(),

also for the grid view

 var willo = Padding(
        padding: const EdgeInsets.all(8.0),
        child: GridView.builder(
          shrinkWrap:true,
          physics: const ClampingScrollPhysics(),
