Server Driven User Interface x Flutter Firebase

This project demonstrates how to build a Server-Driven User Interface (SDUI) using Flutter and Firebase Remote Config. The app dynamically fetches UI configurations from Firebase Remote Config and renders the UI based on the server-provided JSON data.

---

Features

• Dynamic UI Rendering: Fetch UI configurations from Firebase Remote Config and render them dynamically.
• Firebase Integration: Uses Firebase Remote Config, Firebase Authentication, and Firebase Core.
• State Management: Implements flutter_bloc for managing app state.
• Dependency Injection: Uses get_it for dependency injection.

---

Future Improvements

• JSON Response could have been converted custom modular dart classes, currently using Json Decoded response due to limited time.
• Fixed Response JSON Schema across all modules.
• FallBack mechanism if JSON couldn't be parsed.
• Cache responses to save unnecessary APIs.

---

Getting Started - Firebase Remote Config

• Create new firebase project or utilise existing one.
• Under Build >> Remote Config.
• Add new Parameter and give a name dashboard_screen
• Select the data type to be JSON
• Add a default value to the key, here a JSON object
• Save and Publish the response

---

Debug Considerations

• This repository majorly focuses on achieving the SDUI and not on look and feel of the app.
• I've not binded many parameters originally planned for this repository.
• App Theme, Dashboard, Login & Logout has been integrated with bare minimum fields.

---

Personal Opinion

• I genuinely feel its going to be difficult for devs to extend modules overtime, when app needs to be scalled.
• We may encounter run-time errors, could've been caught over pure client-side development process.
• The app only becomes available if there's internet, complete offline mechanism as an option gets ruled out.
• Complete dependency over manual layout of components, instead of Interactive Builders.
• Inaccurate initialization of controllers, subscriptions & listeners.
