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:

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)
          )
        )
      ),
      onPressed: () => null
    )
  ]
)

You can use the ElevatedButton Widget. The elevated button widget has a shape property which you can use as shown in the below snippet.

ElevatedButton(
      style: ButtonStyle(
          shape: MaterialStateProperty.all<RoundedRectangleBorder>(
              RoundedRectangleBorder(
                  borderRadius: BorderRadius.circular(18.0),
                  side: BorderSide(
                      color: Colors.teal, 
                      width: 2.0,
                  ),
              ),
          ),
      ),
      child: Text('Submit'),
      onPressed: () {},
),

Update

Since the left-sided buttons are now deprecated, use the right-sided ones.

Deprecated    -->   Recommended

RaisedButton  -->   ElevatedButton
OutlineButton -->   OutlinedButton
FlatButton    -->   TextButton

  • ElevatedButton

  1. Using StadiumBorder

    ElevatedButton(
      onPressed: () {},
      child: Text('Button'),
      style: ElevatedButton.styleFrom(shape: StadiumBorder()),
    )
    
  2. Using RoundedRectangleBorder

    ElevatedButton(
      onPressed: () {},
      child: Text('Button'),
      style: ElevatedButton.styleFrom(
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(12), // <-- Radius
        ),
      ),
    )
    
  3. Using CircleBorder

    ElevatedButton(
      onPressed: () {},
      child: Text('Button'),
      style: ElevatedButton.styleFrom(
        shape: CircleBorder(),
        padding: EdgeInsets.all(24),
      ),
    )
    
  4. Using BeveledRectangleBorder

    ElevatedButton(
      onPressed: () {},
      child: Text('Button'),
      style: ElevatedButton.styleFrom(
        shape: BeveledRectangleBorder(
          borderRadius: BorderRadius.circular(12)
        ),
      ),
    )
    

OutlinedButton

  1. Using StadiumBorder

    OutlinedButton(
      onPressed: () {},
      child: Text('Button'),
      style: OutlinedButton.styleFrom(
        shape: StadiumBorder(),
      ),
    )
    
  2. Using RoundedRectangleBorder

    OutlinedButton(
      onPressed: () {},
      child: Text('Button'),
      style: OutlinedButton.styleFrom(
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(12),
        ),
      ),
    )
    
  3. Using CircleBorder:

    OutlinedButton(
      onPressed: () {},
      child: Text('Button'),
      style: OutlinedButton.styleFrom(
        shape: CircleBorder(),
        padding: EdgeInsets.all(24),
      ),
    )
    
  4. Using BeveledRectangleBorder

    OutlinedButton(
      onPressed: () {},
      child: Text('Button'),
      style: OutlinedButton.styleFrom(
        shape: BeveledRectangleBorder(
          borderRadius: BorderRadius.circular(12),
        ),
      ),
    )
    

TextButton

TextButton also works similar to ElevatedButton and OutlinedButton, however, you can only see the shapes when the button is pressed.

Since September 2020, Flutter 1.22.0:

Both "RaisedButton" and "FlatButton" are deprecated.

The most up-to-date solution is to use new buttons:

1. ElevatedButton:

Code:

ElevatedButton(
  child: Text("ElevatedButton"),
  onPressed: () => print("it's pressed"),
  style: ElevatedButton.styleFrom(
    primary: Colors.red,
    onPrimary: Colors.white,
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(32.0),
    ),
  ),
)

Don't forget, there's also an .icon constructor to add an icon easily:

ElevatedButton.icon(
  icon: Icon(Icons.thumb_up),
  label: Text("Like"),
  onPressed: () => print("it's pressed"),
  style: ElevatedButton.styleFrom(
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(32.0),
    ),
  ),
)

2. OutlinedButton:

Code:

OutlinedButton.icon(
  icon: Icon(Icons.star_outline),
  label: Text("OutlinedButton"),
  onPressed: () => print("it's pressed"),
  style: ElevatedButton.styleFrom(
    side: BorderSide(width: 2.0, color: Colors.blue),
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(32.0),
    ),
  ),
)

3. TextButton:

You can always use TextButton if you don't want an outline or color fill.

You can simply use RaisedButton


Padding(
  padding: EdgeInsets.only(left: 150.0, right: 0.0),
  child: RaisedButton(
    textColor: Colors.white,
    color: Colors.black,
    child: Text("Search"),
    onPressed: () {},
    shape: new RoundedRectangleBorder(
      borderRadius: new BorderRadius.circular(30.0),
    ),
  ),
)

Output:

You can simply use RaisedButton or you can use InkWell to get a custom button and also properties like onDoubleTap, onLongPress, etc.:

new InkWell(
  onTap: () => print('hello'),
  child: new Container(
    //width: 100.0,
    height: 50.0,
    decoration: new BoxDecoration(
      color: Colors.blueAccent,
      border: new Border.all(color: Colors.white, width: 2.0),
      borderRadius: new BorderRadius.circular(10.0),
    ),
    child: new Center(child: new Text('Click Me', style: new TextStyle(fontSize: 18.0, color: Colors.white),),),
  ),
),

If you want to use the splashColor and highlightColor properties in the InkWell widget, use the Material widget as the parent of the InkWell widget instead of decorating the container (deleting the decoration property). Read about why here.

Different ways to create a rounded button are as follows:

ElevatedButton with ElevatedButton.styleFrom

ElevatedButton(
          style: ElevatedButton.styleFrom(
            shape: RoundedRectangleBorder(
              borderRadius: BorderRadius.circular(30.0),
            ),
          ),
          onPressed: () {},
          child:
              Text("Buy now".toUpperCase(), style: TextStyle(fontSize: 14)),
        ),

ElevatedButton with ButtonStyle

ElevatedButton(
          style: ButtonStyle(
              shape: MaterialStateProperty.all<RoundedRectangleBorder>(
                  RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(50.0),
          ))),
          onPressed: () {},
          child: Text("Submit".toUpperCase()),
        ),

A practical demonstration of a round button can be found in the below Dartpad link:

Rounded Button Demo Examples on DartPad

You can use the below code to make a rounded button with a gradient color.

 Container(
          width: 130.0,
          height: 43.0,
          decoration: BoxDecoration(
            borderRadius: BorderRadius.circular(30.0),
            gradient: LinearGradient(
              // Where the linear gradient begins and ends
              begin: Alignment.topRight,
              end: Alignment.bottomLeft,
              // Add one stop for each color. Stops should increase from 0 to 1
              stops: [0.1, 0.9],
              colors: [
                // Colors are easy thanks to Flutter's Colors class.
                Color(0xff1d83ab),
                Color(0xff0cbab8),
              ],
            ),
          ),
          child: FlatButton(
            child: Text(
              'Sign In',
              style: TextStyle(
                fontSize: 16.0,
                fontFamily: 'Righteous',
                fontWeight: FontWeight.w600,
              ),
            ),
            textColor: Colors.white,
            color: Colors.transparent,
            shape:
                RoundedRectangleBorder(borderRadius: BorderRadius.circular(30.0)),
            onPressed: () {

            },
          ),
        );

Use TextButton instead.

Buttons like the FlatButton, RaisedButton and OutlineButton has been said to be deprecated since October 2020. This is one of the Flutter development team's effort to simplify and make the Flutter API consistent, you can customize its style by using style property.

      TextButton(
        child: Padding(
          padding: const EdgeInsets.only(left: 10.0, right: 10.0),
          child: Text('Text here',
              style: TextStyle(
                  color: Colors.teal,
                  fontSize: 14,
                  fontWeight: FontWeight.w500)),
        ),
        style: TextButton.styleFrom(
          primary: Colors.teal,
          onSurface: Colors.yellow,
          side: BorderSide(color: Colors.teal, width: 2),
          shape: const RoundedRectangleBorder(
              borderRadius: BorderRadius.all(Radius.circular(25))),
        ),
        onPressed: () {
          print('Pressed');
        },
      ),

you can use this code:

ElevatedButton(
      onPressed: () {},
      style: ElevatedButton.styleFrom(
        shape: RoundedRectangleBorder(
            borderRadius: BorderRadius.all(Radius.circular(borderRadius))),
      ),
      child: Text("ok"),
    )

To use any shape in your button, make sure you perform all the code inside the Button widget:

 **shape: RoundedRectangleBorder(
        borderRadius: new BorderRadius.circular(18.0),
        side: BorderSide(color: Colors.red) ),**

If you want make it is square, use BorderRadius.circular(0.0) It automatically makes it into a square.

The button is like this:

Here is the all source code for the give UI screen:

 Scaffold(
    backgroundColor: Color(0xFF8E44AD),
    body: new Center(
      child: Column(
        children: <Widget>[
          Container(
            margin: EdgeInsets.fromLTRB(90, 10, 20, 0),
            padding: new EdgeInsets.only(top: 92.0),
            child: Text(
              "Currency Converter",
              style: TextStyle(
                fontSize: 48,
                fontWeight: FontWeight.bold,
                color: Colors.white,
              ),
            ),
          ),
          Container(
            margin: EdgeInsets.only(),
            padding: EdgeInsets.all(25),
            child: TextFormField(
              decoration: new InputDecoration(
                filled: true,
                fillColor: Colors.white,
                labelText: "Amount",
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(10),
                ),
              ),
            ),
          ),
          Container(
            padding: EdgeInsets.all(25),
            child: TextFormField(
              decoration: new InputDecoration(
                filled: true,
                fillColor: Colors.white,
                labelText: "From",
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(10),
                ),
              ),
            ),
          ),
          Container(
            padding: EdgeInsets.all(25),
            child: TextFormField(
              decoration: new InputDecoration(
                  filled: true,
                  fillColor: Colors.white,
                  labelText: "To",
                  border: OutlineInputBorder(
                    borderRadius: BorderRadius.circular(10),
                  )),
            ),
          ),
          SizedBox(height: 20.0),
          MaterialButton(
            height: 58,
            minWidth: 340,
            shape: RoundedRectangleBorder(
                borderRadius: new BorderRadius.circular(12)),
            onPressed: () {},
            child: Text(
              "CONVERT",
              style: TextStyle(
                fontSize: 24,
                color: Colors.black,
              ),
            ),
            color: Color(0xFFF7CA18),
          ),
        ],
      ),
    ),
  ),
);

You can use this code for a transparent rounded button by passing a transparent color to the color property inside BoxDecoration. eg. color: Colors.transparent. Also, take note that this button makes use of only the Container and GestureDetector widgets.

Container(
    height: 50.0,
    child: GestureDetector(
        onTap: () {},
        child: Container(
            decoration: BoxDecoration(
                border: Border.all(
                    color: Color(0xFFF05A22),
                    style: BorderStyle.solid,
                    width: 1.0,
                ),
                color: Colors.transparent,
                borderRadius: BorderRadius.circular(30.0),
            ),
            child: Row(
                mainAxisAlignment: MainAxisAlignment.center,
                children: <Widget>[
                    Center(
                        child: Text(
                           "BUTTON",
                            style: TextStyle(
                                color: Color(0xFFF05A22),
                                fontFamily: 'Montserrat',
                                fontSize: 16,
                                fontWeight: FontWeight.w600,
                                letterSpacing: 1,
                            ),
                        ),
                    )
                ],
            ),
        ),
    ),

If anybody is looking for complete circular button then I achieved it this way:

Center(
            child: SizedBox.fromSize(
              size: Size(80, 80), // Button width and height
              child: ClipOval(
                child: Material(
                  color: Colors.pink[300], // Button color
                  child: InkWell(
                    splashColor: Colors.yellow, // splash color
                    onTap: () {}, // Button pressed
                    child: Column(
                      mainAxisAlignment: MainAxisAlignment.center,
                      children: <Widget>[
                        Icon(Icons.linked_camera), // Icon
                        Text("Picture"), // Text
                      ],
                    ),
                  ),
                ),
              ),
            ),
          )
RaisedButton(
          child: Text("Button"),
          onPressed: (){},
          shape: RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0),
          side: BorderSide(color: Colors.red))
        )

One of the simplest ways to create a rounded button is to use a FlatButton and then specify the roundness by setting its shape property. Follow the code below

FlatButton(
  padding: EdgeInsets.all(30.0),
  color: Colors.black,
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(20.0)),
  child: child: Text(
    "Button",
    style: TextStyle(color: Colors.white),
  ),
  onPressed: () {
    print('Button pressed');
  },
),

Note: In order to change the roundness adjust the value inside BorderRadius.circular()

You can also use ButtonTheme():

Here is example code -

ButtonTheme(
    minWidth: 200.0,
    shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(18.0),
        side: BorderSide(color: Colors.green)),
    child: RaisedButton(
        elevation: 5.0,
        hoverColor: Colors.green,
        color: Colors.amber,
        child: Text(
            "Place Order",
            style: TextStyle(
                     color: Colors.white, fontWeight: FontWeight.bold),
        ),
        onPressed: () {},
    ),
),

Here is the code for your problem. You just have to take a simple container with a border radius in boxdecoration.

new Container(
    alignment: Alignment.center,
    decoration: BoxDecoration(
        borderRadius: BorderRadius.all(Radius.circular(15.0)),
        color: Colors.blue,
    ),

    child: Row(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
            Padding(
                padding: const EdgeInsets.all(10.0),
                child: new Text(
                    "Next",
                    style: new TextStyle(
                        fontWeight: FontWeight.w500,
                        color: Colors.white,
                        fontSize: 15.0,
                    ),
                ),
            ),
        ],
    ),
),

Now we have an Icon button to achieve a rounded button click and overlay. However, the background color is not yet available, but the same can be achieved by the Circle avatar widget as follows:

CircleAvatar(
    backgroundColor: const Color(0xffF4F3FA),
    child: IconButton(
        onPressed: () => FlushbarHelper.createInformation(
                             message: 'Work in progress...')
                             .show(context),
        icon: Icon(Icons.more_vert),
    ),
),
