Creating engaging onboarding screens is essential for providing users with a smooth introduction to your app. The Fancy OnBoarding screen library allows you to implement visually appealing and intuitive onboarding experiences quickly. In this article, we’ll guide you through the installation, usage, and customization of this library in your Flutter application.

Installation

First, you need to add the FancyOnBoarding dependency to your Flutter project. Follow these steps:

• Open your pubspec.yaml file.
• In the dependencies section, add the following line:

fancy_on_boarding: latest_version

Usage

Import the FancyOnBoarding package and create a list of pages. Here’s how:

Import the Package

import 'package:fancy_on_boarding/fancy_on_boarding.dart';

Create a List of PageModel

Define your onboarding pages using a List. Here’s an analogy to understand this: Think of each PageModel as a chapter in a book, where each chapter introduces a specific topic with visuals and text.

final pageList = [
    PageModel(
        color: const Color(0xFF678FB4),
        heroImagePath: 'assets/png/hotels.png',
        title: Text('Hotels',
            style: TextStyle(fontWeight: FontWeight.w800, color: Colors.white, fontSize: 34.0),
        ),
        body: Text('All hotels and hostels are sorted by hospitality rating',
            textAlign: TextAlign.center,
            style: TextStyle(color: Colors.white, fontSize: 18.0),
        ),
        iconImagePath: 'assets/png/key.png'
    ),
    // Additional PageModels...
];

Pass it into the FancyOnBoarding Widget

Now you’ll use the FancyOnBoarding widget in your build method:

@override
Widget build(BuildContext context) {
    return Scaffold(
        body: FancyOnBoarding(
            doneButtonText: 'Done',
            skipButtonText: 'Skip',
            pageList: pageList,
            onDoneButtonPressed: () {
                Navigator.of(context).pushReplacementNamed(mainPage);
            },
            onSkipButtonPressed: () {
                Navigator.of(context).pushReplacementNamed(mainPage);
            },
        ),
    );
}

Customization and Attributes

The FancyOnBoarding offers various attributes for customization. Here’s a quick overview:

Attribute Name	Example Value	Description
pageList	List<PageModel>	The list of pages to be displayed
doneButtonPressed	()	Function to be called on pressing done button
skipButtonPressed	()	Function to be called on pressing skip button
doneButtonText	Let’s Go	Text content for the done button
skipButtonText	Skip	Text content for the skip button
showSkipButton	true	Show skip button or not, defaults to true
