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

There are many ways to create and use rounded buttons in Flutter, but I’m going to show you some ways that work great in my opinion.

Rounded button using 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),
    ),
  ),
)

Rounded button using InkWell

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),),),
  ),
),

Rounded button using GestureDetector

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,
                            ),
                        ),
                    )
                ],
            ),
        ),
    ),
)

Rounded button using ClipRRect

ClipRRect(
  borderRadius: BorderRadius.circular(40),
  child: RaisedButton(
    onPressed: () {},
    child: Text("Button"),
  ),
)

Rounded button using ClipOval

ClipOval(
  child: RaisedButton(
    onPressed: () {},
    child: Text("Button"),
  ),
)

Rounded button using ButtonTheme

ButtonTheme(
  shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(20)),
  child: RaisedButton(
    onPressed: () {},
    child: Text("Button"),
  ),
)

Rounded button using StadiumBorder

RaisedButton(
  shape: StadiumBorder(),
  onPressed: () {},
  child: Text("Button"),
)
