[icons] Round button with text and icon in flutter

how to have a button with text and icon for the flutter?

I wanted to have a button which looks like icon with a text that is able to put at the bottom of the screen

For example, the icon is like at here: android-button-with-icon-and-text

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:

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

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,
          )
        ],
      ),
    ),
  ),

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
          ],
        ),
      ),
    ),
  ),
)

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,),
      ],
    ),
  ),
),

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)
            ],
          ),

        );
      }
    }

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))
                  ),
