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.

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
          ],
        ),
      ),
    ),
  ),
)

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:
