How to create Onboarding Intro Screen Sliders on Flutter
Introduction
Onboarding intro screen sliders are a crucial part of any mobile application, providing users with a seamless and intuitive experience. Flutter, an open-source mobile app development framework, allows developers to create stunning onboarding screens with ease. In this article, we will explore how to create onboarding intro screen sliders on Flutter, providing a step-by-step guide and code examples to help you get started.
Designing the Onboarding Screen
Before diving into the code, it’s essential to design the onboarding screen. Consider the key elements, such as the background color, font style, and button design. You can use a design tool like Figma or Adobe XD to create a visually appealing design. Once you have a design in place, you can start building the onboarding screen using Flutter.
Creating the Onboarding Screen Slider
To create the onboarding screen slider, you will need to use the `PageView` widget in Flutter. This widget allows you to create a horizontal or vertical scrollable list of pages. Here’s an example code snippet:
“`dart
import ‘package:flutter/material.dart’;
class OnboardingScreen extends StatefulWidget {
@override
OnboardingScreenState createState() => OnboardingScreenState();
}
class _OnboardingScreenState extends State
final _controller = PageController();
@override
Widget build(BuildContext context) {
return Scaffold(
body: PageView(
controller: _controller,
children: [
Container(
color: Colors.blue,
child: Center(
child: Text(‘Slide 1’),
),
),
Container(
color: Colors.red,
child: Center(
child: Text(‘Slide 2’),
),
),
Container(
color: Colors.green,
child: Center(
child: Text(‘Slide 3’),
),
),
],
),
);
}
}
“`
Adding Navigation and Animation
To add navigation and animation to the onboarding screen slider, you can use the `PageView` widget’s built-in features. You can add a navigation bar at the bottom of the screen to indicate the current page. Here’s an updated code snippet:
“`dart
import ‘package:flutter/material.dart’;
class OnboardingScreen extends StatefulWidget {
@override
OnboardingScreenState createState() => OnboardingScreenState();
}
class _OnboardingScreenState extends State
final _controller = PageController();
int _currentPage = 0;
@override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children: [
PageView(
controller: _controller,
onPageChanged: (int page) {
setState(() {
_currentPage = page;
});
},
children: [
Container(
color: Colors.blue,
child: Center(
child: Text(‘Slide 1’),
),
),
Container(
color: Colors.red,
child: Center(
child: Text(‘Slide 2’),
),
),
Container(
color: Colors.green,
child: Center(
child: Text(‘Slide 3’),
),
),
],
),
Positioned(
bottom: 0,
left: 0,
right: 0,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
CircleAvatar(
radius: 5,
backgroundColor: _currentPage == 0 ? Colors.blue : Colors.grey,
),
CircleAvatar(
radius: 5,
backgroundColor: _currentPage == 1 ? Colors.blue : Colors.grey,
),
CircleAvatar(
radius: 5,
backgroundColor: _currentPage == 2 ? Colors.blue : Colors.grey,
),
],
),
),
],
),
);
}
}

Customizing the Onboarding Screen
To customize the onboarding screen, you can add custom fonts, images, and animations. You can also use third-party packages to add more features to your onboarding screen. For example, you can use the `animatedtextkit` package to add animated text to your onboarding screen.
