When to use Vyuh Feature Onboarding
The **Vyuh Feature Onboarding** package delivers a ready‑made, highly configurable onboarding experience that integrates seamlessly with the Vyuh framework. It abstracts the boilerplate of multi‑step tutorials, feature highlights, and permission prompts into a single widget tree that can be dropped into any Vyuh‑based project. By handling navigation, state persistence, and UI theming out of the box, it lets developers focus on the unique value of their app rather than reinventing onboarding screens for each release.
When you’re building a product that requires users to understand core concepts—such as navigating a complex dashboard, configuring initial settings, or granting platform permissions—this package provides a structured way to guide them. The onboarding flow can be composed of any number of pages, each defined with a simple data model that includes title, description, media assets, and optional actions. Because the package respects the Vyuh theming system, the look and feel stay consistent with the rest of the application, and developers can override any visual element through the provided builder callbacks.
From an architectural perspective, Vyuh Feature Onboarding fits neatly into a clean, modular codebase. It lives in the presentation layer, exposing a `VyuhOnboarding` widget that consumes a `OnboardingController`. The controller is a thin wrapper around a `ChangeNotifier` (or any other state manager supported by Vyuh) and can be injected via the framework’s dependency injection container. This design keeps business logic—such as deciding which steps to show based on user profile or feature flags—outside of the UI, making the flow testable and maintainable. The package also stores completion status in the Vyuh persistent storage, so the onboarding sequence is shown only once per user unless explicitly reset.
Getting started is straightforward. After adding the dependency, you register the onboarding controller in your Vyuh module, define the steps in a JSON‑like structure, and place the `VyuhOnboarding` widget at the root of your app or inside a specific route. The package includes sensible defaults for animations, page indicators, and accessibility semantics, but every aspect can be customized via builder functions or theme extensions. For production use, consider enabling the optional `skipOnComplete` flag to automatically bypass the flow for returning users, and use the `onFinish` callback to navigate to the main dashboard or trigger analytics events.
While the package is beginner‑friendly, there are a few production cautions to keep in mind. First, ensure that any heavy media assets (videos, large SVGs) are lazy‑loaded to avoid jank on low‑end devices. Second, if you rely on platform permissions during onboarding, request them only when the user reaches the relevant step to improve acceptance rates. Finally, test the onboarding flow across all supported platforms (iOS, Android, web, desktop) because layout quirks can appear when the same widget tree is rendered in different screen densities. By following these best practices, developers can deliver a polished first‑time experience that reduces churn and accelerates user adoption.
In summary, Vyuh Feature Onboarding is a purpose‑built solution for any Vyuh‑based application that needs a guided introduction for new users. Its modular API, deep integration with Vyuh’s theming and DI system, and extensive customization options make it a solid choice for both rapid prototypes and production‑grade releases. Whether you’re launching a SaaS dashboard, a mobile productivity tool, or a cross‑platform educational app, this package helps you turn onboarding from a chore into a strategic advantage.

Setup notes
Add the package to your project with the command: ``` flutter pub add vyuh_feature_onboarding ``` Then run `flutter pub get`. Register the onboarding controller in your Vyuh module and import the widget where you want the flow to appear.
Requires Flutter 3.10 or higher and Dart SDK >=2.19. The package is built for the Vyuh framework version 2.x and may need adjustments if you are using a custom fork of Vyuh. Works on iOS, Android, web, and desktop platforms.
