sliding_button #

A Flutter package that enables apps to use a slide button to confirm actions.

Installation #

Just follow the basic installation of any flutter plugin by adding the package to the project's pubspec.yaml.

Using this amazing package #

You can start by adding the Sliding Button to your code. All properties inside the constructor are optional so it's fast to test the package. I'll list the properties later.

Simply add the following code and you'll have a fully functional Sliding Button:

import 'package:sliding_button/sliding_button.dart';


After testing the Widget you can look for the properties below that allows you to style the (almost) the hole thing:

import 'package:slide_button/slide_button.dart';

  // Change the HEIGHT of the button. The width is always double.infinity
  buttonHeight = 55,
  // Change the BACKGROUND COLOR of the button
  buttonColor =,
  // Change the TEXT COLOR of the button
  buttonTextColor = Colors.white,
  // Change the TEXT of the button
  buttonText = 'Slide to confirm...',
  // Change the MARGIN between the SLIDE BUTTON and the BUTTON
  slideButtonMargin = 7.5,
  slideButtonColor = Colors.white,
  // Change the ICON COLOR of the ICON that goes inside the SLIDE BUTTON
  slideButtonIconColor =,
  // Change the ICON of the widget that goes inside the SLIDE BUTTON
  slideButtonIcon = Icons.chevron_right,
  // Change the SIZE of the ICON that goes inside the SLIDE BUTTON
  slideButtonIconSize = 30.0,
  // Change the RADIUS of the BUTTON and SLIDE BUTTON
  radius = 4.0,
  // The AMOUNT OF THE TOTAL WIDTH OF THE BUTTON IN % that the user need to slide so we can consider the action as completed
  successfulThreshold = 0.9,
  // The WIDGET that will be shown when the slide action is completed

Using the Sliding Button callbacks #

To get notified when a slide event is completed you'll need provide a VoidCallback to the onSlideSuccessCallback property:

  onSlideSuccessCallback: () {
    // Put your amazing code here

And finally, if you want to reset the state of the Sliding Button you need to access it's state through a GlobalKey:

final GlobalKey<SlidingButtonState> _slideButtonKey = GlobalKey<SlidingButtonState>();


  key: _slideButtonKey,
  onSlideSuccessCallback: () {
    // This will reset the button to the initial state

[0.0.1] - First release with Slide Button 100% functional (maybe with few bugs)

[0.0.2] - Fixes on formatting and added an example

  • First release with Slide Button 100% functional (maybe with few bugs). For more info check the

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
      home: MyHomePage(title: 'Flutter Demo Home Page'),

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  _MyHomePageState createState() => _MyHomePageState();

class _MyHomePageState extends State<MyHomePage> {

  final GlobalKey<SlideButtonState> _slideButtonKey = GlobalKey<SlideButtonState>();

  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.

  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // Here we take the value from the MyHomePage object that was created by
        // the method, and use it to set our appbar title.
        title: Text(widget.title),
      body: Center(
        // Center is a layout widget. It takes a single child and positions it
        // in the middle of the parent.
        child: Column(
          // Column is also a layout widget. It takes a list of children and
          // arranges them vertically. By default, it sizes itself to fit its
          // children horizontally, and tries to be as tall as its parent.
          // Invoke "debug painting" (press "p" in the console, choose the
          // "Toggle Debug Paint" action from the Flutter Inspector in Android
          // Studio, or the "Toggle Debug Paint" command in Visual Studio Code)
          // to see the wireframe for each widget.
          // Column has various properties to control how it sizes itself and
          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
          children: <Widget>[
