How to Make a Round Button

Circle button css

For div tag there is already default property display:block given by browser. For anchor tag there is not display property given by browser. You need to add display property to it. That's why use display:block or display:inline-block. It will work.

.btn {  display:block;  height: 300px;  width: 300px;  border-radius: 50%;  border: 1px solid red;  }

<a class="btn" href="#"><i class="ion-ios-arrow-down"></i></a>

How to make a round button?

Create an xml file named roundedbutton.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="rectangle">
    <solid android:color="#eeffffff" />
    <corners android:bottomRightRadius="8dp"
        android:bottomLeftRadius="8dp"  
        android:topRightRadius="8dp"
        android:topLeftRadius="8dp"/>
</shape>

Finally set that as background to your Button as android:background = "@drawable/roundedbutton"

If you want to make it completely rounded, alter the radius and settle for something that is ok for you.

Create a rounded button / button with border-radius in Flutter

1. Solution Summary

FlatButton and RaisedButton are deprecated.

So, you can use shape which placed in the style property, for TextButton and ElevatedButton.

There are some changes since Flutter 2.0:

• style: the property type has changed to ButtonStyle
• shape: the property type has changed to MaterialStateProperty<T>

2. Rounded Button

Inside the style property exists the shape property:

style: ButtonStyle(
  shape: MaterialStateProperty.all<RoundedRectangleBorder>(
    RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(18.0),
      side: BorderSide(color: Colors.red)
    )
  )
)

Square Button

For a square button you can use ElevatedButton or otherwise add:

style: ButtonStyle(
  shape: MaterialStateProperty.all<RoundedRectangleBorder>(
    RoundedRectangleBorder(
      borderRadius: BorderRadius.zero,
      side: BorderSide(color: Colors.red)
    )
  )
)

Complete Example

Row(
  mainAxisAlignment: MainAxisAlignment.end,
  children: [
    TextButton(
      child: Text(
        "Add to cart".toUpperCase(),
        style: TextStyle(fontSize: 14)
      ),
      style: ButtonStyle(
        padding: MaterialStateProperty.all<EdgeInsets>(EdgeInsets.all(15)),
        foregroundColor: MaterialStateProperty.all<Color>(Colors.red),
        shape: MaterialStateProperty.all<RoundedRectangleBorder>(
          RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(18.0),
            side: BorderSide(color: Colors.red)
          )
        )
      ),
      onPressed: () => null
    ),
    SizedBox(width: 10),
    ElevatedButton(
      child: Text(
        "Buy now".toUpperCase(),
        style: TextStyle(fontSize: 14)
      ),
      style: ButtonStyle(
        foregroundColor: MaterialStateProperty.all<Color>(Colors.white),
        backgroundColor: MaterialStateProperty.all<Color>(Colors.red),
        shape: MaterialStateProperty.all<RoundedRectangleBorder>(
          RoundedRectangleBorder(
            borderRadius: BorderRadius.zero,
            side: BorderSide(color: Colors.red)
          )
        )

We can create a circular button by FloatingActionButton widget.

 return Container(
      alignment: Alignment.center,
