The definition of Flutter Button

Buttons are the graphical control element that provides a user to trigger an event such as taking actions, making choices, searching things, and more. Then, they, as Flutter button, can be placed anywhere in our UI like dialogs, forms, cards, toolbars, etc.

Moreover, Buttons are the Flutter widgets, which is a part of the material design library. Flutter also provides several types of buttons that have different shapes, styles, and features.

Some of Available Flutter Button Features

1. Flat Button

Most important, it is a text label button that does not have much decoration and displayed without any elevation. Moreover, the flat button has two required properties that are: child and onPressed(). It is mostly used in toolbars, dialogs, as well as inline with other content. By default, the flat button has no color, then, its text is black. But, we can use color to the button and text using color and textColor attributes, respectively.

For example:

Firstly, open the main.dart file and replace it with the below code.

import 'package:flutter/material.dart';  
void main() {  
class MyApp extends StatefulWidget {  
  _MyAppState createState() => _MyAppState();  
class _MyAppState extends State<MyApp> {  
  Widget build(BuildContext context) {  
    return MaterialApp(  
      home: Scaffold(  
          appBar: AppBar(  
            title: Text('Flutter FlatButton Example'),  
          body: Center(child: Column(children: <Widget>[  
              margin: EdgeInsets.all(25),  
              child: FlatButton(  
                child: Text('SignUp', style: TextStyle(fontSize: 20.0),),  
                onPressed: () {},  
              margin: EdgeInsets.all(25),  
              child: FlatButton(  
                child: Text('LogIn', style: TextStyle(fontSize: 20.0),),  
                color: Colors.blueAccent,  
                textColor: Colors.white,  
                onPressed: () {},  

Then, Output:

If we run this app, we will see the following screen:

2. Floating Action Button

Above all, a FAB button is a circular icon button that triggers the primary action in our application. It is also the most used button in today’s applications. We can use this Flutter button for adding, refreshing as well as sharing the content. Flutter also suggests using at most one FAB button per screen. Moreover, there are two types of Floating Action Button:

FloatingActionButton: Above all, it creates a simple circular floating button with a child widget inside it. Moreover, it must have a child parameter to display a widget.

FloatingActionButton.extended: To clarify, it creates a wide floating button along with an icon and a label inside it. Instead of a child, it uses labels and icon parameters.

For example, open the main.dart file and replace it with the below code.

  1. import ‘package:flutter/material.dart’;  
  3. void main() {  
  4.   runApp(MyApp());  
  5. }  
  7. class MyApp extends StatefulWidget {  
  8.   @override  
  9.   _MyAppState createState() => _MyAppState();  
  10. }  
  12. class _MyAppState extends State<MyApp> {  
  13.   @override  
  14.   Widget build(BuildContext context) {  
  15.     return MaterialApp(home: Scaffold(  
  16.       appBar: AppBar(  
  17.         title: Text(“FAB Button Example”),  
  18.         backgroundColor: Colors.blue,  
  19.         actions: <Widget>[  
  20.           IconButton(icon: Icon(Icons.camera_alt), onPressed: () => {}),  
  21.           IconButton(icon: Icon(Icons.account_circle), onPressed: () => {})  
  22.         ],  
  23.       ),  
  24.       floatingActionButton: FloatingActionButton(  
  25.         child: Icon(Icons.navigation),  
  26.         backgroundColor: Colors.green,  
  27.         foregroundColor: Colors.white,  
  28.         onPressed: () => {},  
  29.       ),  
  30.       /*floatingActionButton:FloatingActionButton.extended(  
  31.         onPressed: () {},  
  32.         icon: Icon(Icons.save),  
  33.         label: Text(“Save”),  
  34.       ), */  
  35.     ),  
  36.     );  
  37.   }  
  38. }  

Then, output:

Run the application in android emulator, then, it will give the UI similar to the following screenshot. The second image also is an output of the FAB.extended button. Its coding also can be seen in the above code’s comment section.

  1. import ‘package:flutter/material.dart’;  
  3. void main() => runApp(MyApp());  
  5. class MyApp extends StatelessWidget {

  12.         ),  
  13.         body: Center(  
  14.           child: MyStatefulWidget(),  
  15.         ),  
  16.       ),  
  17.     );  
  18.   }  
  19. }  
  20. double _speakervolume = 0.0;  
  22. class MyStatefulWidget extends StatefulWidget {  
  23.   MyStatefulWidget({Key key}) : super(key: key);  
  25.   @override  
  26.   _MyStatefulWidgetState createState() => _MyStatefulWidgetState();  
  27. }  
  29. class _MyStatefulWidgetState extends State<MyStatefulWidget> {  
  30.   Widget build(BuildContext context) {  
  31.     return Column(  
  32.       mainAxisSize: MainAxisSize.min,  
  33.       children: <Widget>[  
  34.         IconButton(  
  35.           icon: Icon(Icons.volume_up),  
  36.           iconSize: 50,  
  37.           color: Colors.brown,  
  38.           tooltip: ‘Increase volume by 5’,  
  39.           onPressed: () {  
  40.             setState(() {  
  41.               _speakervolume += 5;  
  42.             });  
  43.           },  
  44.         ),  
  45.         Text(‘Speaker Volume: $_speakervolume’)  
  46.       ],

4. Button Bar

Above all, Flutter provides the flexibility to arrange the buttons in a bar or a row.Moreover, ButtonBar widget also contains three properties: alignment, children, and mainAxisSize.

  • Thirdly, mainAxisSize attribute is used to provide the horizontal space for the button bar.

For example:

Firstly, open the main.dart file and replace it with the below code.

import 'package:flutter/material.dart';  
  void main() {  
  runApp(MaterialApp( home: MyApp(),));  


class MyApp extends StatefulWidget {  
  _State createState() => _State();  
class _State extends State<MyApp> {  
  Widget build(BuildContext context) {  
    return Scaffold(  
        appBar: AppBar(  
          title: Text('Flutter ButtonBar Example'),  
        body: Padding(  
            padding: EdgeInsets.all(10),  
            child: Column(  
              children: <Widget>[  
                  padding: EdgeInsets.all(15),  
                  child: new ButtonBar(  
                    mainAxisSize: MainAxisSize.min,  
                    children: <Widget>[  
                        child: new Text('Javatpoint'),  
                        color: Colors.lightGreen,  
                          onPressed: () {/** */},  
                        child: Text('Flutter'),  
                        color: Colors.lightGreen,  
                        onPressed: () {/** */},  
                        child: Text('MySQL'),  
                        color: Colors.lightGreen,
