Hi kibettitus2020 saw your answer listed below- 

Question where do I insert it. I put the original code in this link

 

class RestaurantPage extends StatelessWidget { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text("Restaurant"), backgroundColor: Colors.red, ), body: SingleChildScrollView( child: Column( children: <Widget>[ Padding( padding: EdgeInsets.only(top: 10, left: 10.0), child: Row( mainAxisAlignment: MainAxisAlignment.spaceBetween, children: <Widget>[ IconButton( icon: Icon(Icons.arrow_back_ios), color: Colors.white, onPressed: () { Navigator.of(context).pop(); }, ), Container( width: 125.0, child: Row( mainAxisAlignment: MainAxisAlignment.spaceBetween, children: <Widget>[ IconButton( icon: Icon(Icons.filter_list), color: Colors.white, onPressed: () {}, ), IconButton( icon: Icon(Icons.menu), color: Colors

Using Flutter ver 3.3.6 the following flutter program  gets

No MediaQuery widget ancestor found. Someone gave me an example of this but I have no idea where to put it  my code.

return MediaQuery(

    data: MediaQueryData(),

    child: MaterialApp(

    home: Scaffold(

    body: SizedBox(

    height: MediaQuery.of(context).size.height,

    child: const Dashboard(),

   ),

)

My Original code listed below

import 'package:flutter/material.dart';
void main() {runApp(const FoodList());}

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

@override
Widget build(BuildContext context) {
return const MaterialApp(
home: FoodList(),
);
}
}



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

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("Food List"),
),
body: ListView(
children: const <Widget>[
ListTile(
title: Text("Food Item 1"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 2"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 3"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 4"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 5"),
trailing: Checkbox(value: false, onChanged: null),
),
ElevatedButton(
onPressed: null,
child: Text('Submit'),
)
],
),
);
}
}

Using Flutter Version 3.3.6 - 

My code below - I got this message which I don't understand

No MediaQuery widget ancestor found.
Scaffold widgets require a MediaQuery widget ancestor.
The specific widget that could not find a MediaQuery ancestor was:
  Scaffold
The ownership chain for the affected widget is: "Scaffold ← FoodList ← [root]"
No MediaQuery ancestor could be found starting from the context that was passed to MediaQuery.of(). This can happen because you have not added a WidgetsApp, CupertinoApp, or MaterialApp widget (those widgets introduce a MediaQuery), or it can happen if the context you use comes from a widget above those widgets.

import 'package:flutter/material.dart';
void main() {runApp(const FoodList());}

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

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("Food List"),
),
body: ListView(
children: const <Widget>[
ListTile(
title: Text("Food Item 1"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 2"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 3"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 4"),
trailing: Checkbox(value: false, onChanged: null),
),
ListTile(
title: Text("Food Item 5"),
trailing: Checkbox(value: false, onChanged: null),
),
ElevatedButton(
onPressed: null,
child: Text('Submit'),
)
],
),
);
}
}

My flutter program using Flutter version 3.3.6 below not working can someone find out. See code below: Other people have helped ,but they are using the older flutter version so it won't work.

I get the following red screen message - 

No MediaQuery widget answer found.
Scaffold widgets require a MediaQuery widget ancestor.
The specific widgets require a MediaQuery ancestor was:

Scaffold
The ownership chain for the affected widget is "Scaffold - Foodlist - [root]
No MediaQuery ancestor could be found starting from the context that was passed to MediaQuery.of().
This can happen because you have not added a WidgetApp,
CupertinoApp or MaterialApp widget (those widgets introduca MediaQuery), or it can happen if the context you use comes from a widget above those widgets. See also

Here is the code listed below -

import 'package:flutter/material.dart';
void main() {runApp(const FoodList());}

class FoodList extends StatelessWidget {
