圆形按钮与文字和图标在颤动

You can achieve that by using a FlatButton that contains a Column (for showing a text below the icon) or a Row (for text next to the icon), and then having an Icon Widget and a Text widget as children.

Here's an example:

class MyPage extends StatelessWidget {


@override
Widget build(BuildContext context) =>
Scaffold(
appBar: AppBar(
title: Text("Hello world"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
FlatButton(
onPressed: () => {},
color: Colors.orange,
padding: EdgeInsets.all(10.0),
child: Column( // Replace with a Row for horizontal icon + text
children: <Widget>[
Icon(Icons.add),
Text("Add")
],
),
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: () => {},
tooltip: 'Increment',
child: Icon(Icons.add),
),
);
}

This will produce the following:

EDIT 1: With Flutter 1.20 release Flutter Team did breaking changes introducing new buttons. So the below mentioned button types are deprecated. Use TextButton instead of FlatButton and ElevatedButton instead of RaisedButton.

TextButton.icon(onPressed: null, icon: null, label: null);
Elevated.icon(onPressed: null, icon: null, label: null);

See breaking changes for buttons and their themes here

Note: FlatButton and RaisedButton is DEPRECATED

You can simply use named constructors for creating different types of buttons with icons. For instance

FlatButton.icon(onPressed: null, icon: null, label: null);
RaisedButton.icon(onPressed: null, icon: null, label: null);

But if you have specfic requirements then you can always create custom button with different layouts or simply wrap a widget in GestureDetector.

Use Column or Row in a Button child, Row for horizontal button, Column for vertical, and dont forget to contain it with the size you need:

Container(
width: 120.0,
height: 30.0,
child: RaisedButton(
color: Color(0XFFFF0000),
child: Row(
children: <Widget>[
Text('Play this song', style: TextStyle(color: Colors.white),),
Icon(Icons.play_arrow, color: Colors.white,),
],
),
),
),

You can do something like,

RaisedButton.icon( elevation: 4.0,
icon: Image.asset('images/image_upload.png' ,width: 20,height: 20,) ,
color: Theme.of(context).primaryColor,
onPressed: getImage,
label: Text("Add Team Image",style: TextStyle(
color: Colors.white, fontSize: 16.0))
),

Screenshot:

SizedBox.fromSize(
size: Size(56, 56), // button width and height
child: ClipOval(
child: Material(
color: Colors.orange, // button color
child: InkWell(
splashColor: Colors.green, // splash color
onTap: () {}, // button pressed
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.call), // icon
Text("Call"), // text
],
),
),
),
),
)

If you need a button like this:

You can use RaisedButton and use the child property to do this. You need to add a Row and inside row you can add a Text widget and an Icon Widget to achieve this. If you want to use png image, you can use similar widget to achieve this.

RaisedButton(
onPressed: () {},
color: Theme.of(context).accentColor,
child: Padding(
padding: EdgeInsets.fromLTRB(
SizeConfig.safeBlockHorizontal * 5,
0,
SizeConfig.safeBlockHorizontal * 5,
0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Text(
'Continue',
style: TextStyle(
fontSize: 20,
fontWeight: FontWeight.w700,
color: Colors.white,
),
),
Icon(
Icons.arrow_forward,
color: Colors.white,
)
],
),
),
),

If You need the text to be centered, and the image to be besides it, like this:

Then You can achieve it with this widget tree:

RaisedButton(
onPressed: () {},
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Expanded(child: Text(
'Push it! '*10,
textAlign: TextAlign.center,
),),
Image.network(
'https://picsum.photos/250?image=9',
),
],
),
),

Full example available on my dartpad.dev (link).

The way i usually do it is by embedding a Row inside the Raised button:

class Sendbutton extends StatelessWidget {
@override
Widget build(BuildContext context) {
return RaisedButton(
onPressed: () {},
color: Colors.black,
textColor: Colors.white,
child: Row(
children: <Widget>[
Text('Send'),
Icon(Icons.send)
],
),


);
}
}

Congrats to the previous answers... But I realised if the icons are in a row (say three icons as represented in the image above), you need to play around with columns and rows.

Here is the code

 Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
FlatButton(
onPressed: () {},
child: Icon(
Icons.call,
)),
FlatButton(
onPressed: () {},
child: Icon(
Icons.message,
)),
FlatButton(
onPressed: () {},
child: Icon(
Icons.block,
color: Colors.red,
)),
],
),
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Text(
'   Call',
),
Text(
'Message',
),
Text(
'Block',
style: TextStyle(letterSpacing: 2.0, color: Colors.red),
),
],
),
],
),

Here is the result

The FlatButton, RaisedButton and OutlineButton widgets have been replaced by TextButton, ElevatedButton, and OutlinedButton respectively.

Just put this code below as Button. Also the accepted answer is updated in September, 2021.

TextButton.icon(
style: TextButton.styleFrom(
textStyle: TextStyle(color: Colors.blue),
backgroundColor: Colors.white,
shape:RoundedRectangleBorder(
borderRadius: BorderRadius.circular(24.0),
),
),
onPressed: () => {},
icon: Icon(Icons.send_rounded,),
label: Text('Contact me',),
),

In the Newest Version of Flutter, I think you can use Just IconButton Widget like this :

@override
Widget build(BuildContext context) {
return Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
IconButton(
icon: const Icon(Icons.volume_up),
onPressed: () {},
),
Text('Volume')
],
);
}

Hope this helps out, learn more about it from this documentation.

Flutter 2.4:

The best recommended way is using ShapeDecoration

Here is a example using an Inkwell (simulating a button, but you can use a button instead and get same result).

InkWell(
onTap: (){},
child: Container(
width: 50,
height: 50,
decoration: ShapeDecoration(
shape: CircleBorder(), //here we set the circular figure
color: Colors.red
),
child: Center(
child: Icon(
Icons.email,
size: 30,
color: Colors.white,
)
),
)
)

These are the posibles shapes in ShapeDecoration:

RoundedRectangleBorder(),
BeveledRectangleBorder(),
ContinuousRectangleBorder(),
CircleBorder(),

I hope this will help out. I am using flutter 2.10.1

ElevatedButton.icon(onPressed: null, icon: null, label: null);
