Stac

Abstract

1. Introduction

Instead of hard-coding everything in your app, you write your UI using Stac's intuitive Dart DSL. Your server then delivers this UI as a JSON payload, and Stac automatically renders it natively on the client at runtime.

It's super easy to get started. You just need to initialize Stac and tell it which screen to load.

2. Objective

Stac is a Server-Driven UI (SDUI) framework for Flutter, enabling you to create stunning, cross-platform applications dynamically with JSON. Build and update your app's UI in real-time with ease and flexibility!

This project demonstrates how Dart, Flutter, Android can be applied to a real-world Mobile App Development problem.

3. Key Features / Modules

• Instant updates: Push UI changes straight from your server. No app store waiting rooms.
• Familiar Dart syntax: Write your server UI using our purely Dart DSL. It feels just like writing traditional Flutter code!
• Native rendering: Stac translates your server's payload into lightning-fast native Flutter widgets on the client.
• Prebuilt components: Comes with a massive library of ready-to-use standard Flutter widgets.
• Network requests: Trigger API calls and manage data directly from your server payload.
• Navigation: Control routing, open dialogs, and trigger bottom sheets from the backend.
• Forms & validation: We handle the messy form state and validation for you.
• Dynamic theming: Change colors, fonts, and layouts on the fly using StacTheme.
• Smart caching: Built-in screen caching so your app feels blazing fast, even on flaky networks.
• Custom widgets: Need a custom chart or native integration? Easily build and register your own UI components.

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which framework is used and why (native vs cross-platform)?
2. How is app state managed across screens?
3. Where is the data stored — locally, Firebase or a REST backend?
4. How are permissions (camera, location, storage) handled?
5. How would you publish this app to the Play Store / App Store?
