+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Flutter application called "bully" targeting multiple platforms (Android, iOS, Linux, macOS, Web, Windows).
+
+## Build Commands
+
+```bash
+# Get dependencies
+flutter pub get
+
+# Run the app (debug mode)
+flutter run
+
+# Run on a specific device
+flutter run -d <device_id>
+
+# Build for release
+flutter build apk          # Android
+flutter build ios          # iOS
+flutter build web          # Web
+flutter build windows      # Windows
+flutter build macos        # macOS
+flutter build linux        # Linux
+
+# Analyze code for issues
+flutter analyze
+
+# Run all tests
+flutter test
+
+# Run a single test file
+flutter test test/widget_test.dart
+
+# Run tests with coverage
+flutter test --coverage
+```
+
+## Features
+
+### Analyse de cibles de tir
+- Support de cibles concentriques (anneaux) et silhouettes
+- Chargement d'images de cibles depuis la galerie ou la caméra
+- Détection automatique du centre et du rayon de la cible
+
+### Calibration des cibles
+- Ajustement manuel du centre, du rayon et du nombre d'anneaux (1-10)
+- **Calibration individuelle des anneaux** : cliquer sur un anneau pour l'ajuster indépendamment
+- Slider global pour redimensionner tous les anneaux proportionnellement
+- Visualisation en temps réel des zones de score
+
+### Détection d'impacts
+- **Ajout manuel** : cliquer sur l'image pour placer un impact
+- **Détection automatique** : algorithme de détection de blobs avec paramètres ajustables
+  - Seuil de luminosité
+  - Taille min/max des impacts
+  - Circularité minimale
+  - Ratio de remplissage (distingue les trous pleins des cercles vides)
+- **Détection par références** : sélectionner 2-4 impacts manuellement, l'algorithme apprend leurs caractéristiques et détecte les impacts similaires
+
+### Calcul des scores
+- Score automatique basé sur la position de l'impact dans les zones
+- Cibles concentriques : score de 10 (centre) à 1 (bord externe)
+- Support des anneaux calibrés individuellement pour un calcul précis
+- Affichage du score total et de la distribution
+
+### Analyse de groupement
+- Calcul du diamètre de groupement
+- Visualisation du cercle de groupement
+- Centre de groupement affiché
+
+### Statistiques
+- **Zones chaudes (Heat Map)** : visualisation en brouillard avec gradient bleu (froid) à rouge (chaud)
+- **Précision** : pourcentage de précision, score moyen
+- **Écart-type** : dispersion horizontale et verticale
+- **Distribution régionale** : répartition des tirs par quadrant
+- Filtrage par période : session, semaine, mois, toutes les sessions
+
+### Historique des sessions
+- Sauvegarde des sessions avec date, score, notes
+- Visualisation des sessions passées
+- Suppression de sessions
+
+### Interface utilisateur
+- Thème sombre adapté au tir
+- Support multilingue (Français)
+- Interface responsive pour mobile et desktop
+
+## Architecture
+
+Standard Flutter project structure:
+- `lib/` - Dart source code (entry point: `lib/main.dart`)
+- `test/` - Widget and unit tests
+- Platform directories: `android/`, `ios/`, `linux/`, `macos/`, `web/`, `windows/`
+
+The app uses `flutter_lints` for static analysis (configured in `analysis_options.yaml`).

+# bully
+
+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Learn Flutter](https://docs.flutter.dev/get-started/learn-flutter)
+- [Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Flutter learning resources](https://docs.flutter.dev/reference/learning-resources)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
