      ),
    );

class BallPage extends StatelessWidget {
  @override

    return Scaffold(
      backgroundColor: Colors.blue,
      appBar: AppBar(
        backgroundColor: Colors.blue.shade900,

  }
}

I hope this will put an end to all the doubts to the newbies to this course.

What I did was what was done in the previous lesson and I know by experience that my method is better because keeping the AppBar() in the topmost widget helps navigate the code better. When you will go on to make more and more pages later on and would want the same AppBar in every page, it does not make sense to keep creating new widgets for such small things.

Verdict : Both the answers are absolutely correct. It is how you prefer to do it.

agreed

import 'dart:math';

import 'package:flutter/material.dart';

void main() {
runApp(MyApp());
}

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

@OverRide
_MyAppState createState() => _MyAppState();
}

class _MyAppState extends State {
int imageNO = 1;

void changeImage() {
setState(() {
imageNO = Random().nextInt(5) +1;
});
}

@OverRide
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
backgroundColor: Colors.blue,
appBar: AppBar(
centerTitle: true,
backgroundColor: Colors.blue[800],
title: Text("Ask me Every thing"),
),
body: Center(
child: Expanded(
child: TextButton(
onPressed: () {
changeImage();
},
child: Image.asset('images/ball$imageNO.png'),
),
),
),
),
);
}
}

Hello ruudkalis,

I always use “centerTitle: true;” in order to center it.

like this:

appBar: AppBar(
backgroundColor: Colors.blue.shade900,
title: Text('Ask Me Anything'),
centerTitle: true;
),

Idk why her code don’t have it and the title is in center.. but..

Hope I helped u.

Regards

Oh ComOn man !! She already told us in her lectures about it.. it is because she is debugging in IOS Simulator. for your knowlwdge ios always shows the title in the center of appbar. but android doesn't , you have to do manually like you do it already

//please anything wrong with this code

import 'package:flutter/material.dart';

void main() {
runApp(MagicPage());
}

class MagicPage extends StatelessWidget {

@OverRide
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
backgroundColor: Colors.blue,
appBar: AppBar(
backgroundColor: Colors.blue.shade900,
title: Text("Ask Me Anything"),
centerTitle: true,

class BallPage extends StatefulWidget {

}

class _BallPageState extends State {
@OverRide
Widget build(BuildContext context) {

}
}

This is my solution, worked like charm
`import 'package:flutter/material.dart';

void main() => runApp(
MaterialApp(
home: Ballpage(),
),
);

class Ballpage extends StatelessWidget {
const Ballpage({Key? key}) : super(key: key);

@OverRide
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.blue,
appBar: AppBar(
title: Text('Ask me anyhing'), backgroundColor: Colors.blue.shade900),
body: Container(),
);
}
}
`

//please anything wrong with this code

class BallPage extends StatefulWidget { @OverRide _BallPageState createState() => _BallPageState(); }

class _BallPageState extends State { @OverRide Widget build(BuildContext context) { return Container(); } }

Use a stateless widget instead of a stateful widget, yes it is going to work but you dont need to save a state yet. so keep it simple

// this code shows images in a sequence and when the images is completed then images shows from the start again

void main() {
  return runApp(
    MaterialApp(
      home: Scaffold(
        backgroundColor: Colors.amber,

          title: Center(child: Text('Magic 8 Ball')),
        ),
        body: _BallPoll(),
      ),
    ),
  );
}

class _BallPoll extends StatefulWidget {
  @override
  _BallPollState createState() => _BallPollState();
}

class _BallPollState extends State<_BallPoll> {
  int newBallImage = 1;
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Container(
        child: TextButton(
          onPressed: () {
            setState(() {
              newBallImage++;
              if (newBallImage == 6) {
                newBallImage = 1;

I have successfully completed the assignment to create a stateless widget as taught by Angela Yu in the Flutter development course on Udemy.

Overall, this assignment has been a valuable learning opportunity, allowing me to practice creating stateless widgets and improving my skills in customizing widget behavior and appearance. I am excited to continue exploring Flutter development through this course and further expand my knowledge.

I wish to connecting with other flutter developers

This is my code!!

import 'package:flutter/material.dart';

runApp(MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
backgroundColor: Colors.blue,
appBar: AppBar(
title: Text(
'Ask Me Anything',
style: TextStyle(
fontSize: 20,
fontWeight: FontWeight.bold,
color: Colors.white,
fontFamily: 'SourceCodePro'),
),
centerTitle: true,
backgroundColor: Colors.blue.shade900,
),
body: Ball())));
}

class Ball extends StatefulWidget {
const Ball({super.key});

@OverRide
State createState() => _BallState();
}

class _BallState extends State {
@OverRide
int Magicball = 1;

void randomAnswerGenerator() {
setState(() {
Magicball = Random().nextInt(5) + 1;
});
}

Widget build(BuildContext context) {
return TextButton(
onPressed: () {
randomAnswerGenerator();
},
