Button styling in flutter - flutter-layout

Question

Executed program picture I need help. I want to make the button click circular instead of rectangular.
This is the flutter dart code that I've provided, I want to know what attribute I should change or insert for making my question possible.
import 'package:flutter/material.dart';
import 'dart:math';
void main() {
runApp(MaterialApp(
title: 'Ask me anything',
home: Scaffold(
appBar: AppBar(
title: Text('Ask me anything'),
centerTitle: true,
backgroundColor: Colors.blue[700],
),
backgroundColor: Colors.blue[800],
body: MyApp(),
),
));
}
class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);
#override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
int ballNumber = 1;
#override
Widget build(BuildContext context) {
return Center(
child: Expanded(
child: TextButton(
style: ButtonStyle(enableFeedback: true,shape: ),
onPressed: () => setState(() {
ballNumber = Random().nextInt(5) + 1;
}),
child: Image.asset(
'images/ball$ballNumber.png',
width: 400,
// height: 200,
),
),
));
}
}

You can either change button style, or just wrap the image with GestureDetector.
Round Button
ElevatedButton(
style: ElevatedButton.styleFrom(
shape: const CircleBorder(),
padding: const EdgeInsets.all(50),
),
onPressed: () {},
child: const FittedBox(
child: Text('Round Button'),
),
),
ElevatedButton(
style: ButtonStyle(
shape: MaterialStateProperty.all<CircleBorder>(
const CircleBorder(),
),
padding: MaterialStateProperty.all<EdgeInsets>(
const EdgeInsets.all(50),
),
),
onPressed: () {},
child: const FittedBox(
child: Text('Round Button'),
),
),
GestureDetector
GestureDetector(
onTap: () {
setState(() {
ballNumber = Random().nextInt(5) + 1;
});
},
child: Image.asset('images/ball$ballNumber.png'),
),
