I'm currently developing an Android app in Flutter. How can I add a rounded button?
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 toButtonStyle
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)
)
)
),
onPressed: () => null
)
]
)
You can use the RaisedButton Widget. The raised 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: () {},
),
Since, the left sides buttons are now deprecated, use the right sided ones.
Deprecated --> Recommended
RaisedButton --> ElevatedButton
OutlineButton --> OutlinedButton
FlatButton --> TextButton
ElevatedButton
Using StadiumBorder
ElevatedButton( onPressed: () {}, child: Text('Button'), style: ElevatedButton.styleFrom(shape: StadiumBorder()), )
Using RoundedRectangleBorder
ElevatedButton( onPressed: () {}, child: Text('Button'), style: ElevatedButton.styleFrom( shape: RoundedRectangleBorder( borderRadius: BorderRadius.circular(12), // <-- Radius ), ), )
Using CircleBorder
ElevatedButton( onPressed: () {}, child: Text('Button'), style: ElevatedButton.styleFrom( shape: CircleBorder(), padding: EdgeInsets.all(24), ), )
Using BeveledRectangleBorder
ElevatedButton( onPressed: () {}, child: Text('Button'), style: ElevatedButton.styleFrom( shape: BeveledRectangleBorder( borderRadius: BorderRadius.circular(12) ), ), )
OutlinedButton
Using StadiumBorder
OutlinedButton( onPressed: () {}, child: Text('Button'), style: OutlinedButton.styleFrom( shape: StadiumBorder(), ), )
Using RoundedRectangleBorder
OutlinedButton( onPressed: () {}, child: Text('Button'), style: OutlinedButton.styleFrom( shape: BeveledRectangleBorder( borderRadius: BorderRadius.circular(12), ), ), )
Using CircleBorder
:
OutlinedButton( onPressed: () {}, child: Text('Button'), style: OutlinedButton.styleFrom( shape: CircleBorder(), padding: EdgeInsets.all(24), ), )
Using BeveledRectangleBorder
OutlinedButton( onPressed: () {}, child: Text('Button'), style: OutlinedButton.styleFrom( shape: BeveledRectangleBorder( borderRadius: BorderRadius.circular(12), ), ), )
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.
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),
),
),
)
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),
),
),
)
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:
More info: RSCoder
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 .
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: () {
},
),
);
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,
),
),
)
],
),
),
),
)
you can use this code:
ElevatedButton(
onPressed: () {},
style: ElevatedButton.styleFrom(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(borderRadius))),
),
child: Text("ok"),
)
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
],
),
),
),
),
),
)
Different ways to create a rounded button are as follows:
FlatButton Button with Shape RoundedRectangleBorder
FlatButton(
minWidth: 260,
height: 60,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.red)),
color: Colors.white,
textColor: Colors.red,
padding: EdgeInsets.all(8.0),
onPressed: () {},
child: Text(
"Add to Cart".toUpperCase(),
style: TextStyle(
fontSize: 14.0,
),
),
),
RaisedButton Button with Shape RoundedRectangleBorder
RaisedButton(
padding:
EdgeInsets.only(left: 100, right: 100, top: 20, bottom: 20),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(28.0),
side: BorderSide(color: Colors.red)),
onPressed: () {},
color: Colors.red,
textColor: Colors.white,
child: Text("Buy now".toUpperCase(),
style: TextStyle(fontSize: 14)),
),
RaisedButton Button with Shape StadiumBorder()
RaisedButton(
padding:
EdgeInsets.only(left: 100, right: 100, top: 20, bottom: 20),
shape: StadiumBorder(),
onPressed: () {},
child: Text("Button"),
)
RaisedButton Button with ClipRRect
ClipRRect(
borderRadius: BorderRadius.circular(40),
child: RaisedButton(
padding: EdgeInsets.only(
left: 100, right: 100, top: 20, bottom: 20),
onPressed: () {},
child: Text("Button"),
),
)
RaisedButton Button with ClipOval
ClipOval(
child: RaisedButton(
onPressed: () {},
child: Text("Button"),
),
),
RaisedButton Button with ButtonTheme
ButtonTheme(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20)),
child: RaisedButton(
onPressed: () {},
child: Text("Button"),
),
)
A practical demonstration of a round button can be found in the below dartpad link:
After the Null safety, use ElevatedButton not RaisedButton because RaisedButton is depreciated as the docs says.
child: ElevatedButton(
onPressed: () {},
child: const Text('Add item to the list'),
style: ButtonStyle(
backgroundColor:
MaterialStateProperty.all<Color>(Common.buttonColor),
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
),
),
),
),
You should probably familiarize yourself with this page of the docs in particular: rounding corners .
The docs show you how to change the styling of a component and the equivalent styling in css, if you are familiar with that already.
RaisedButton(
child: Text("Button"),
onPressed: (){},
shape: RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0),
side: BorderSide(color: Colors.red))
)
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: () {},
),
),
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()
customElevatedButton({radius, color}) => ElevatedButton.styleFrom(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(radius == null ? 100 : radius),
),
primary: color,
);
Widget saveIcon() => iconsStyle1(
Icons.save,
);
// Common icon style
iconsStyle1(icon) => Icon(
icon,
color: white,
size: 15,
);
ElevatedButton.icon(
icon: saveIcon(),
style:
customElevatedButton(color: Colors.green[700]),
label: Text('Save',
style: TextStyle(color: Colors.white)),
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),
),
),
Here is another solution:
Container(
height: MediaQuery.of(context).size.height * 0.10,
width: MediaQuery.of(context).size.width,
child: ButtonTheme(
minWidth: MediaQuery.of(context).size.width * 0.75,
child: RaisedButton(
shape: RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(25.0),
side: BorderSide(color: Colors.blue)),
onPressed: () async {
// Do something
},
color: Colors.red[900],
textColor: Colors.white,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Button Text,
style: TextStyle(fontSize: 24)),
),
),
),
),
You can create a custom view and put it inside a GestureDetector for it to behave like a button. The benefit is that you can provide endless types of custom decoration (including making it round with specified radius) to the container.
Container(
width: yourWidth,
height: yourHeight ,
decoration: BoxDecoration(
borderRadius: radius,
gradient: yourGradient,
border: yourBorder),
child: FlatButton(
onPressed: {} (),
shape: RoundedRectangleBorder(borderRadius: radius),
.......
and use the same radius.
Another cool solution that works in 2021:
TextButton(
child: Padding(
padding: const EdgeInsets.all(5.0),
child: Text('Follow Us'.toUpperCase()),
),
style: TextButton.styleFrom(
backgroundColor: Colors.amber,
shadowColor: Colors.red,
elevation: 2,
textStyle: TextStyle(fontSize: 18, fontWeight: FontWeight.bold),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(5.0),)
),
onPressed: () {
print('Pressed');
},
),
addButton() {
return Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.symmetric(vertical: 10.0),
child: SizedBox(
height: 45,
width: 200,
child: ElevatedButton.icon(
onPressed: () async {},
style: ButtonStyle(
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.circular(30.0),
)),
elevation: MaterialStateProperty.all(1),
backgroundColor: MaterialStateProperty.all(Colors.blue),
),
icon: Icon(Icons.add, size: 18),
label: Text("Add question"),
),
),
),
],
);
}
you can use this style for your elevatedButton to make it circular
style: ButtonStyle(
elevation: MaterialStateProperty.all(8.0),
backgroundColor:
MaterialStateProperty.all(Constants().orangeColor),
textStyle: MaterialStateProperty.all(
TextStyle(
fontSize: 16.0,
),
),
shape: MaterialStateProperty.all<CircleBorder>(
CircleBorder(),
),
shadowColor: MaterialStateProperty.all(Constants().orangeColor),
),
With Flutter version 2, try this
ElevatedButton(
style: ButtonStyle(
shape: MaterialStateProperty.all<OutlinedBorder>(
RoundedRectangleBorder(
side:
BorderSide(width: 1.0, color: Colors.red,
borderRadius:
BorderRadius.circular(5.0),),),
backgroundColor: MaterialStateProperty.all<Color>(Colors.red),
foregroundColor: MaterialStateProperty.all<Color>(Colors.green),
elevation:
MaterialStateProperty.all<double>(8.0),
padding: MaterialStateProperty.all<EdgeInsetsGeometry>(
const EdgeInsets.symmetric(
horizontal: 15.0,
vertical: 10.0),),),
onPressed: (){},
child: Text('Button'),)
Container with round border color:
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10),
border: Border.all(color: Colors.red),
),
child: Text("Some Text"),
)
You can always use a material button if you are using the Material App as your main Widget.
Padding(
padding: EdgeInsets.symmetric(vertical: 16.0),
child: Material(
borderRadius: BorderRadius.circular(30.0),//Set this up for rounding corners.
shadowColor: Colors.lightBlueAccent.shade100,
child: MaterialButton(
minWidth: 200.0,
height: 42.0,
onPressed: (){//Actions here//},
color: Colors.lightBlueAccent,
child: Text('Log in', style: TextStyle(color: Colors.white),),
),
),
)
In Flutter, the
Container()
widget is used for styling your widget. Using theContainer()
widget, you can set a border or rounded corner of any widget.
If you want to set any type of styling and set the decoration, put that widget into the Container()
widget. That provides many properties to the decoration.
Container(
width: 100,
padding: EdgeInsets.all(10),
alignment: Alignment.center,
decoration: BoxDecoration(
color: Colors.blueAccent,
borderRadius: BorderRadius.circular(30)), // Make rounded corner
child: Text("Click"),
)
Wrap a TextButton in a Container widget like the below code snippet:
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(5),
border: Border.all(color: Colors.black),
),
child: TextButton(
onPressed: () {
// To do
},
child: Text("Go to Change Language Screen "),
),
)
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');
},
),
MaterialButton
then,RoundedRectangleBorder
Given in Shape
Like this,MaterialButton(
onPressed: () {},
minWidth: MediaQuery.of(context).size.width * 0.4,
height: 34,
color: colorWhite,
highlightColor: colorSplash,
splashColor: colorSplash,
visualDensity: VisualDensity.compact,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(4),
side: BorderSide(
color: colorGrey,
width: 0.6,
),
),
child: Text("CANCEL"),
),
There is another way to do this-Just use FloatingActionButton for Proper Rounded Button.
Scaffold(
appBar: AppBar(
title: const Text('Floating Action Button'),
),
body: const Center(child: Text('Press the button below!')),
floatingActionButton: FloatingActionButton(
onPressed: () {
// Add your onPressed code here!
},
backgroundColor: Colors.green,
child: const Icon(Icons.navigation),
),
)
Try this:
SizedBox(
height: 40.0,
child: MaterialButton(
child: Text("Button"),
color: Colors.blue,
disabledColor: Colors.blue,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(
Radius.circular(10.0), // Change your border radius here
),
),
onPressed: () {},
),
),
RawMaterialButton is better suited I think.
RawMaterialButton(
onPressed: () {},
elevation: 2.0,
fillColor: Colors.white,
child: Icon(
Icons.pause,
size: 35.0,
),
padding: EdgeInsets.all(15.0),
shape: CircleBorder(),
)
In the new update flutter 3.0
flutter uses Material 3
guidelines.
According to which the default border of buttons are rounded .
Default Button
ElevatedButton(
onPressed: () {}, child: const Text("Default Button ")),
Button with Border Radius Zero
ElevatedButton(
style: ElevatedButton.styleFrom(
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.zero)),
onPressed: () {},
child: const Text("Border Radius Zero ")),
Button with custom border radius
ElevatedButton(
style: ElevatedButton.styleFrom(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(50))),
onPressed: () {},
child: const Text("Border Radius Custom ")),
FilledButton
, TextButton
and the like.Refer https://m3.material.io/components/all-buttons for button style.
