How to make Circular Buttons in Flutter (2022)

Last updated on January 28, 2022 A Goodman Loading... One comment

Buttons are an indispensable part of mobile applications. In Flutter, buttons are rectangular in shape by default. However, in some cases, you may want your buttons to be circular to accentuate and blend in with the surrounding layout best.

This article shows you a few elegant ways to create circular buttons (also called round buttons) in Flutter. Without any further ado, let’s get started.

The point here is to give the elevated button an equal width and height, then set its shape to CircleBorder().

Preview:

The code:

ElevatedButton(
          child: const Text(
            'Button',
            style: TextStyle(fontSize: 24),
          ),
          onPressed: () {},
          style: ElevatedButton.styleFrom(
              fixedSize: const Size(200, 200)
              shape: const CircleBorder(), 
          ),
),

Using MaterialButton

The code:

MaterialButton(
        color: Colors.blue,
        shape: const CircleBorder(),
        onPressed: () {},
        child: const Padding(
          padding: EdgeInsets.all(100),
          child: Text(
            'A circle button',
            style: TextStyle(color: Colors.white, fontSize: 24),
          ),
        ),
)

Output:

Using GestureDetector + CircleAvatar

Example:

GestureDetector(
            onTap: () {
              print('Button tapped');
            },
            child: const CircleAvatar(
              radius: 100,
              backgroundColor: Colors.indigo,
              child: Text(
                'A Button',
                style: TextStyle(fontSize: 30),
              ),
)),

Screenshot:

Using ElevatedButton + Container

In the old days, the ElevatedButton widget doesn’t provide an option for sizing it (the ElevatedButton.styleFrom method has no parameter named fixedSize). That’s why this approach was useful in the past. Nowadays, it seems more complex than necessary. However, I think it is still worth trying.

The code:

ElevatedButton(
        style: ElevatedButton.styleFrom(
            shape: const CircleBorder(), primary: Colors.red),
        child: Container(
          width: 200,
          height: 200,
          alignment: Alignment.center,
          decoration: const BoxDecoration(shape: BoxShape.circle),
          child: const Text(
            'I am a button',
            style: TextStyle(fontSize: 24),
          ),
        ),
        onPressed: () {},
)

Output:

Using ClipRRect + SizedBox + ElevatedButton

Another interesting technique for implementing a circle button in Flutter.

The code:

ClipRRect(
          borderRadius: BorderRadius.circular(120),
          child: SizedBox(
            width: 240,
            height: 240,
            child: ElevatedButton.icon(
              icon: const Icon(
                Icons.camera,
                size: 40,
              ),
              label: const Text(
                'Camera',
                style: TextStyle(fontSize: 25),
              ),
              onPressed: () {},
            ),
          ),
),

Output:

An Old Method for RaisedButton (Legacy)

The RaisedButton widget is deprecated and only appears in old apps. If you’re working with a new Flutter project, use ElevatedButton instead.

Wrap a RaisedButton widget inside a square Container and use the BorderRadius class.

Sample code:

import 'package:flutter/material.dart';
void main() => runApp(const MyApp());

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        // Removing the debug banner when running on simulators
        debugShowCheckedModeBanner: false,
        title: 'An Aweasome App',
        home: Scaffold(
          appBar: AppBar(
            title: const Text('Home'),
          ),
          body: Center(
            child: Column(
              children: <Widget>[
                // just an empty SizedBox to add some spacing
                const SizedBox(
                  height: 30,
                ),

                SizedBox(
                    // set width equal to height to make a square
                    width: 200,
                    height: 200,
                    child: RaisedButton(
                      color: Colors.orange,
                      shape: RoundedRectangleBorder(
                          // set the value to a very big number like 100, 1000...
                          borderRadius: BorderRadius.circular(100)),
                      child: const Text('I am a button'),
                      onPressed: () {},
                    ))
              ],
            ),
          ),
        ));
  }
}
