System Requirements Document (SRD)

Project Name: lime-flutter

1. Introduction

The lime-flutter project is a Flutter-based mobile application designed to provide users with seamless access to live news updates via a web interface. This document outlines the system requirements for the project, ensuring clarity and alignment with the development goals.

The application leverages Flutter's webview_flutter package to embed a web-based news platform directly into the app, offering a smooth and interactive user experience. This SRD is tailored for Vishal Salate, based in India, and assumes locale-specific defaults such as IST timezone, INR currency, and user preferences for modern, responsive design.

2. System Overview

The lime-flutter application is a lightweight, user-friendly mobile app that integrates a live news website using WebView. The app is designed to:

• Provide real-time access to news updates.
• Ensure a seamless and responsive browsing experience.
• Handle errors gracefully and improve user experience with loading indicators.

The system architecture includes:

• Frontend: Flutter framework for mobile app development.
• Backend: No backend integration is required as the app directly loads a web-based news platform.
• Error Handling: Displays user-friendly messages for web resource errors.
• Progress Indicator: Enhances user experience during page load.

3. Functional Requirements

As User:

• I should be able to view live news updates via the embedded WebView.
• I should see a loading spinner while the page is loading.
• I should receive a notification (e.g., SnackBar) if the page fails to load due to an error.

4. User Personas

1. User:

• Description: The primary user of the app who wants to access live news updates.
• Goals:
  • Access real-time news seamlessly.
  • Experience a smooth and responsive interface.
  • Be informed of any issues during page load.
• Pain Points:
  • Delays in page loading.
  • Lack of error notifications.

5. Visuals Colors and Theme

Unique Color Palette:

The lime-flutter project adopts a modern and vibrant color scheme to reflect the dynamism of live news updates.

6. Signature Design Concept

Interactive News Globe

The lime-flutter homepage will feature a bold, unforgettable design: an Interactive News Globe.

• Visuals:

  • A 3D globe rotates slowly in the center of the screen, with glowing pins marking major news locations around the world.
  • Each pin represents a category (e.g., Politics, Sports, Technology).

• Interactions:

  • Users can swipe or tap on a pin to zoom into that region, revealing headlines and summaries.
  • Smooth transitions and animations create a dynamic experience.

• Micro-Interactions:

  • Hovering over a pin causes it to pulse gently.
  • Clicking a pin triggers a ripple effect across the globe.

• Color Shifts:

  • The globe’s background subtly changes based on the time of day (e.g., warm tones for morning, cool tones for night).

This design ensures the app leaves a lasting impression and engages users with an immersive experience.

7. Non-Functional Requirements

• Performance:
  • The app must load the embedded website within 3 seconds on a standard 4G connection.
• Scalability:
  • The app should support future enhancements, such as additional features or integrations.
• Reliability:
  • The app must handle web resource errors gracefully and notify users.
• Usability:
  • The app should be intuitive and easy to navigate for all users.

8. Tech Stack

Frontend:

• Flutter framework for mobile app development.

Backend:

• No backend integration required.

AI Tools (Optional for future enhancements):

• GPT 5.4 for user-friendly responses.
• Google Nano Banana for image generation.

Local Orchestration:

• Docker and docker-compose for containerization.

9. Assumptions and Constraints

Assumptions:

• Users have access to a stable internet connection.
• The embedded website is optimized for mobile viewing.
• The app will primarily be used in India, with locale-specific defaults.

Constraints:

• The app relies on the availability and performance of the embedded website.
• Limited offline functionality as the app is web-dependent.

10. Glossary

• WebView: A component that allows mobile apps to display web content.
• SnackBar: A lightweight notification that appears at the bottom of the screen.
• Flutter: An open-source UI toolkit for building natively compiled applications.
• Docker: A platform for developing, shipping, and running applications in containers.
