Testing the triple backticks again for the flutter code to be readable. If this doesn't work no idea how to do it in oneclass. I put triple backticks one line above code and second triple backticks below my code after the last line.

 

```

import 'package:flutter/material.dart'; import 'package:google_fonts/google_fonts.dart';
import 'package:todolist/pages/tasklist/tasklist.dart'; import 'package:todolist/pages/tasklistdetails/tasklistdetails.dart';
void main() {   runApp(const MyApp()); }
class MyApp extends StatelessWidget {   const MyApp({super.key});
  @override   Widget build(BuildContext context) {     return MaterialApp(         title: 'Flutter Demo',         theme: ThemeData(           primarySwatch: Colors.blue,           textTheme: GoogleFonts.robotoCondensedTextTheme(),         ),         initialRoute: '/tasklist',         routes: {           '/tasklist': ((context) =>               const TaskListPage(title:"Task List1 Page")),           '/tasklistdetails': ((context) =>               const TaskListDetailsPage(title: "Task List Details Page"))         });   } }
class MyHomePage extends StatefulWidget {   const MyHomePage({super.key, required this.title});   final String title;   @override   State<MyHomePage> createState() => _MyHomePageState(); }
class _MyHomePageState extends State<MyHomePage> {   @override   Widget build(BuildContext context) {     return Scaffold(       appBar: AppBar(         title: Text(widget.title),       ),       body: const Text('Task list page'),       floatingActionButton: Theme(         data: Theme.of(context).copyWith(splashColor: Colors.amber),         child: FloatingActionButton(           onPressed: () =>{Navigator.pop(context)},           tooltip: 'Increment',           child: const Icon(Icons.add),         ),       ), // This trailing comma makes auto-formatting nicer for build methods.     );   } } ```

For flutter 3.3.2 fixed the return statement now having issues with the following lines - lib/main.dart(16,18): error G4127D1E8: The getter '_formkey' isn't defined for the class 'MyAppState'. [D:\form_widget5\build\windows\flutter\flutter_assemble.vcxproj]

Difference between VS Code and Android Studio Eel version when it comes to flutter program. See screenshot below. See line 22 on the left side of the screen is VS Code the right side is Android Studio

VS Code is ok with this line

initialRoute: '/tasklist',

while Android Studio is complaining about it and wants it to be replaced

as 

initialRoute: '/task-list',

Is there a reason why Android Studio would want a hyphen.

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'),
)
],
),
);
}
}
