How to Add Circular Elevated Button in Flutter: A Step-by-Step Guide

Introduction:

Flutter is a popular open-source mobile app development framework created by Google. It’s known for its simplicity, flexibility, and speed in building beautiful and scalable mobile apps. One of the essential UI components in Flutter is the button. In this article, we’ll explore how to add a circular elevated button in your Flutter app.

What are Elevated Buttons in Flutter?

Before we dive into adding a circular elevated button, let’s understand what elevated buttons are in Flutter. Elevated buttons are a type of button in Flutter that changes the color based on the state of the button. They can be used as a call-to-action (CTA) button or as a navigation button. By default, elevated buttons have a rectangular shape, but we can customize them to fit our design requirements.

Why Add a Circular Elevated Button?

There may be situations where a circular button is more visually appealing or fits better with your app’s design. For example, if you’re building an app with a modern UI design or an onboarding screen, a circular elevated button can make your app look more professional and visually appealing.

How to Add a Circular Elevated Button in Flutter

Adding a circular elevated button in Flutter is relatively easy. You can do it by creating a custom Flutter widget using the DecoratedBox widget and the ClipOval widget.

Here’s an example code to get you started:

“dart


import 'package:flutter/material.dart';





class CircularElevatedButton extends StatelessWidget {
  final String text;
  final Color color;
  CircularElevatedButton({required this.text, required this.color});
  @override
  Widget build(BuildContext context) {
    return DecoratedBox(
      decoration: BoxDecoration(
        shape: BoxShape.circle,
        color: color,
      ),
      child: ClipOval(
        child: TextButton(
          onPressed: () {
            // Your button's logic goes here
          },
          child: Text(text),
        ),
      ),
    );
  }
}

In this example, we've created a custom CircularElevatedButton widget that takes two parameters: text and color. The DecoratedBox widget is used to create a box with a circular shape and the specified color. The ClipOval widget is used to clip the content of the button to a circle. Finally, the TextButton widget is used to create the button with the specified text and color.
