# AdNotes

A new Flutter project.

AdNotes is a simple **Flutter** note-taking application that stores data locally in a JSON file within the app's document directory.  

It follows a clean architecture with a **Repository layer** for data persistence and a **Service layer** for business logic and reactive state management.

## Getting Started

## Features

This project is a starting point for a Flutter application.

- ✏️ **Create notes** – add a title and description.

- 📝 **Edit notes** – update existing notes using the same form.

- 🗑 **Delete notes** – remove notes with a confirmation dialog.

- 📄 **Note preview** – displays a list of notes with title, a short preview of the description, and creation date.

- 🔄 **Reactive UI** – changes are immediately reflected in the note list through streams.

## Architecture

- **`NotesRepository`** – responsible for reading and writing notes from/to a local JSON file.

- **`NotesManagingService`** – manages the state of notes in a `BehaviorSubject` and saves changes through the repository.

- **`GetIt`** – used for dependency injection to easily access services and repositories throughout the app.

- **`rxdart`** – used for reactive state management with `BehaviorSubject`, providing an always-up-to-date stream of notes.

- **UI layer** uses `StreamBuilder` to listen for changes in the notes stream and rebuild the interface automatically.
