Supabase reconfigure

[AkiTheMemeGod]

This pull request introduces several significant improvements and architectural changes to the Entangled Flutter messaging app. The most notable updates are the removal of Firebase dependencies in favor of Supabase, a comprehensive overhaul of the project documentation, and the implementation of a robust in-app notification system with real-time capabilities and UI enhancements.

Major highlights:

• Migrates backend integration from Firebase to Supabase, including configuration and initialization.
• Adds a detailed, production-quality README.md that outlines architecture, features, and best practices.
• Implements an in-app notification flyout system for real-time, actionable notifications.
• Updates routing to include a dedicated notifications screen.
• Cleans up legacy imports and configuration files related to Firebase.

Backend Migration and Configuration

• Removed all Firebase dependencies and configuration, including firebase_core, firebase_options.dart, and related initialization logic in main.dart. Added a new supabase_config.dart for Supabase credentials and initialization. (lib/config/firebase_options.dart [1] lib/main.dart [2] lib/config/supabase_config.dart [3] lib/models/chat_model.dart [4]

In-App Notification System

• Implemented an in-app notification flyout using Riverpod providers and overlay entries, enabling real-time, interactive notifications that navigate to the relevant chat on tap. (lib/app.dart [1] [2] [3]
• Added notification models and providers to support notification state management and UI updates. (lib/app.dart lib/app.dartR1-R16)

Documentation and Project Overview

• Rewrote the README.md with a thorough project overview, architecture diagrams, feature breakdowns, technology stack, design patterns, security considerations, and deployment instructions. (README.md README.mdL1-R300)

Routing and Navigation

• Added a dedicated notifications screen and corresponding route, updating the app's routing configuration to support notification-related navigation. (lib/config/routes.dart [1] [2] [3]

Permissions and Platform Integration

• Added the Android notification permission (POST_NOTIFICATIONS) to the app manifest to support push notifications on Android 13+. (android/app/src/main/AndroidManifest.xml android/app/src/main/AndroidManifest.xmlR2-R3)

These changes collectively modernize the codebase, enhance the user experience with real-time notifications, and position the project for scalable, cross-platform deployment using Supabase as the backend.
