+# Changelog
+
+## [v0.0.1] - 2026-01-29
+
+### Ajouté
+-   **Interface d'Analyse** :
+    -   Implémentation d'un bouton de sauvegarde "Morphing" : le bouton flottant se transforme en un bouton large en bas de page lors du défilement.
+    -   Ajout de la gestion du défilement et de l'espacement pour une meilleure ergonomie.
+    -   Visualisation des impacts et statistiques de groupement.
+-   **Support Desktop (Windows)** :
+    -   Configuration de la base de données SQLite pour fonctionner sur Windows via `sqflite_common_ffi`.
+    -   Initialisation conditionnelle selon la plateforme.
+
+### Corrigé
+-   **Crash Windows** : Résolution du plantage dû à l'initialisation manquante de la factory de base de données FFI.
+-   **Dépendances** : Fixation de la version de `sqflite_common_ffi` à `2.3.3` pour contourner un problème de cache/corruption avec la version `2.4.0+2`.
+-   **UI/UX** :
+    -   Correction des débordements de texte ("zebra stripes") dans le bouton de sauvegarde lors de l'animation grâce à `FittedBox`.
+    -   Optimisation de l'affichage du titre "Groupement" dans les statistiques pour éviter les dépassements sur petits écrans.
+    -   Nettoyage des appels redondants (`super.initState`) et correction de la structure des widgets (`Stack` mal fermé).
+
+### Historique des Commits
+-   `db7160b` - +désactivation (2026-01-29)
+-   `f1a8eef` - ajout correctif (2026-01-28)

+# Bully - Analyseur de Cible
 
-A new Flutter project.
+Application Flutter multiplateforme pour l'analyse et le suivi de vos séances de tir.
 
-## Getting Started
+## Fonctionnalités Principales
 
-This project is a starting point for a Flutter application.
+*   **Capture et Analyse** : Prenez une photo de votre cible et analysez vos impacts.
+*   **Détection Automatique** : Utilise des algorithmes pour détecter automatiquement les impacts de balle sur la cible.
+*   **Calibration** : Outils de calibration précis pour définir la taille et le centre de la cible, assurant des mesures exactes.
+*   **Statistiques Détaillées** :
+    *   Calcul du score total.
+    *   Analyse du groupement (H+L, diamètre moyen).
+    *   Visualisation graphique de la dispersion.
+*   **Historique** : Sauvegardez vos sessions avec des notes et consultez votre progression au fil du temps.
+*   **Interface Intuitive** : Design moderne et fluide, avec un bouton de sauvegarde dynamique qui s'adapte à votre navigation.
 
-A few resources to get you started if this is your first Flutter project:
+## Détails Techniques
 
-- [Learn Flutter](https://docs.flutter.dev/get-started/learn-flutter)
+*   **Framework** : Flutter (Compatible Android, iOS, Windows, Linux, macOS).
-- [Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+*   **Base de Données** : SQLite (via `sqflite` et `sqflite_common_ffi` pour le support Desktop).
-- [Flutter learning resources](https://docs.flutter.dev/reference/learning-resources)
+*   **Graphiques** : `fl_chart` pour la visualisation des données.
+*   **Architecture** : Provider pour la gestion d'état.
 
-For help getting started with Flutter development, view the
+## Installation
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
+
-samples, guidance on mobile development, and a full API reference.

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.

+# Documentation du Projet Bully
+
+Bienvenue dans la documentation développeur de l'application **Bully**.
+
+Ce projet est une application Flutter d'analyse de cibles de tir (Impact Detection).
+
+## Architecture
+
+Le code source est organisé dans le dossier `lib/` selon les couches suivantes :
+
+- **Features (`lib/features`)** : Contient les écrans et la logique UI (Vues/Pages). C'est ici que réside l'interface utilisateur.
+- **Services (`lib/services`)** : Services "métier" et utilitaires (traitement d'image, calculs, etc.). Indépendant de l'UI.
+- **Data (`lib/data`)** : Gestion des données (Modèles, Base de données locale, Repositories).
+
+## Sections de la Documentation
+
+Pour plus de détails sur chaque partie, consultez les sections dédiées :
+
+- 🏗️ **[Services (Logique Métier)](services/README.md)** : Documentation des services comme le traitement d'image et le calcul de score.
+- 📱 **[Vues & Features (UI)](features/README.md)** : Documentation des écrans principaux (ex: Analyse).
+- 💾 **[Base de Données & Modèles](data/README.md)** : Structure des données et persistance.
+
+## Pour commencer
+
+1. Assurez-vous d'avoir Flutter installé.
+2. Lancez `flutter run` pour démarrer l'application.

+# Data & Persistance
+
+Cette couche gère la sauvegarde et la récupération des données.
+
+## Base de Données
+L'application utilise une base de données locale (probablement SQLite/Drift ou Hive, à vérifier dans `lib/data/database`).
+
+## Modèles (`lib/data/models`)
+Les classes représentant les objets métier persistés.
+
+Exemples probables :
+- `Session` : Une session de tir.
+- `Impact` : Un impact de balle sur la cible.
+- `Target` : Configuration d'une cible.
+
+## Repositories (`lib/data/repositories`)
+Le pattern Repository est utilisé pour abstraire la source de données (DB locale, API distante, etc.) du reste de l'application.

+# Features & Vues
+
+Cette section documente les écrans principaux de l'application et leur organisation.
+
+## Écrans Principaux
+
+### Analysis (`lib/features/analysis`)
+C'est le cœur de l'application. Il permet à l'utilisateur de prendre une photo ou choisir une image pour analyser les impacts.
+
+- **AnalysisScreen** (`analysis_screen.dart`): L'écran principal qui orchestre la capture et l'affichage des résultats.
+- **AnalysisProvider** (`analysis_provider.dart`): Gestionnaire d'état (State Management) pour cet écran. Il fait le pont entre la vue et les services.
+
+## Structure d'une Feature
+Chaque feature est généralement composée de :
+- `_screen.dart` : Le Widget de la page.
+- `_provider.dart` : La logique d'état (ChangeNotifier, Bloc, etc.).
+- `widgets/` : Widgets spécifiques à cette feature.

+# Services
+
+Les services contiennent la logique métier de l'application, isolée de l'interface utilisateur.
+
+## Liste des Services Principaux
+
+| Service | Description | Fichier |
+| :--- | :--- | :--- |
+| **ImageProcessingService** | Gère le traitement lourd des images (filtres, détection). | `lib/services/image_processing_service.dart` |
+| **DistortionCorrection** | Corrige la distorsion de perspective des cibles. | `lib/services/distortion_correction_service.dart` |
+| **ScoreCalculator** | Calcule le score en fonction des impacts détectés. | `lib/services/score_calculator_service.dart` |
+| **StatisticsService** | Génère des statistiques sur les sessions de tir. | `lib/services/statistics_service.dart` |
+
+## Exemple d'utilisation (Fictif)
+
+```dart
+// Exemple d'appel au service de calcul de score
+final calculator = ScoreCalculatorService();
+final score = calculator.calculate(impacts);
+```
