ElPoyo	7258509528	feat: amélioration de l'assistant IA logisticien et de la gestion des containers - Backend (Cloud Functions) : - Mise à jour de `firebase-functions` vers la version `7.2.5`. - Amélioration de la sécurité et de la flexibilité des clés API Gemini (support des variables d'environnement `.env` et `.env.local`). - Optimisation de la recherche d'équipements avec une stratégie multi-passes (exacte, par tokens, puis catégorielle/fuzzy). - Ajout de nouveaux outils pour l'IA : `check_container_availability` et `check_container_availability_batch` pour vérifier la disponibilité des flight-cases. - Implémentation d'un post-traitement automatique suggérant des containers complets si tous leurs équipements internes sont requis par l'événement. - Amélioration de la résilience aux erreurs 429/503 de Gemini avec une stratégie d'exponential backoff. - Frontend (Flutter) : - Mise à jour du service `AiEquipmentAssistantService` pour gérer les métadonnées détaillées des containers (rationale, items manquants/matchings, disponibilité). - Refonte de l'interface `AiEquipmentAssistantDialog` : - Affichage enrichi des containers dans le récapitulatif. - Ajout de la possibilité de sélectionner/désélectionner manuellement les containers (notamment ceux marqués comme "partiels"). - Amélioration visuelle (ombres, bordures, icônes de statut de disponibilité). - Marquage de l'assistant en mode "BETA". - Général : - Mise à jour du `.gitignore` pour inclure `functions/.env.local`. - Correction de typos et amélioration du logging de debug dans le backend.	2026-05-25 23:00:43 +02:00
ElPoyo	7fc28f4374	feat: (BETA) Amélioration de l'assistant IA logisticien (Gemini) et support des documents - Amélioration de l'IA (Cloud Functions) : - Mise à jour du modèle vers `gemini-3.1-flash-lite` et augmentation de la limite des résultats de recherche à 50. - Optimisation de la gestion des outils : augmentation du nombre d'appels simultanés (`MAX_TOOL_CALLS_PER_ITERATION`) à 40. - Refonte du système de recherche d'équipements avec une stratégie en deux passes (recherche précise puis catégorielle avec normalisation agressive). - Nouvelles consignes strictes pour la gestion des unités uniques (quantité de 1 par ID) et priorité aux flight cases (containers). - Ajout d'une gestion de retry avec temporisation pour les erreurs de quota (429) et de surcharge (503). - Support de l'analyse de documents joints (devis, listes) envoyés en `inlineData`. - Interface de l'Assistant (`AiEquipmentAssistantDialog`) : - Ajout de la possibilité de joindre des documents (PDF, images, texte) via `FilePicker` pour analyse par l'IA. - Implémentation d'une vue de logs de debug détaillée pour suivre le raisonnement de l'IA et les appels d'outils. - Amélioration visuelle de la discussion : bulles de message stylisées et structuration automatique des réponses (sections "Matériel ajouté" vs "Matériel non trouvé"). - Nouvelles options de confirmation : "Tout ajouter" ou "Ajouter sans alternatives". - Modèles et Services : - Mise à jour de `EventEquipment` pour inclure un champ `rationale` (justification du choix de l'équipement). - Correction dans `EventAssignedEquipmentSection` pour ajouter automatiquement les équipements enfants lors de l'ajout d'un container proposé par l'IA. - Ajout de la gestion des logs et des documents dans `AiEquipmentAssistantService`. - UI Divers : - Mise à jour de `EquipmentFormPage` pour clarifier le comportement de l'identifiant (auto-génération recommandée).	2026-05-25 20:33:59 +02:00
ElPoyo	89ab3673c4	### Key Changes: AI Equipment Proposal (`functions/aiEquipmentProposal.js`): - Updated Gemini model to `gemini-3.1-flash-lite-preview` and updated the API key. - Increased `MAX_TOOL_ITERATIONS` from 12 to 20. - Added a new tool `list_equipment_by_category` to allow the AI to browse equipment when specific searches fail. - Enhanced the system prompt with instructions to handle typos via category exploration and authorized more creative equipment suggestions based on event descriptions. - Improved the user prompt to include more event context (name, location, notes, and options). - Set `responseMimeType: 'application/json'` in the generation config for better reliability. - Improved error logging and user-facing error messages for timeouts. UI & Pagination (`lib/views/`): - ContainerFormPage: Replaced `StreamBuilder` with a paginated list using `DataService` for equipment selection. Added a scroll controller to support infinite scrolling and updated UI colors to use the newer `withValues` API. - EquipmentSelectionDialog: - Increased pagination limit from 25 to 50 items. - Implemented `_checkIfMoreItemsNeeded` logic to automatically fetch more pages if filters (like hiding conflicting items) leave the view too empty. - Added a `NotificationListener` to the `ListView` to trigger pagination on scroll. - Fixed minor encoding issues in comments. --- ### Proposed Commit Message: feat: Mise à jour du modèle Gemini et optimisation de la sélection du matériel avec pagination - Mise à jour du modèle d'IA vers `gemini-3.1-flash-lite-preview` et augmentation de la limite d'itérations des outils à 20. - Ajout de l'outil `list_equipment_by_category` pour permettre à l'IA d'explorer les alternatives en cas d'échec de recherche textuelle. - Enrichissement du prompt système et du contexte envoyé à l'IA (nom, lieu, notes et options de l'événement). - Implémentation de la pagination dans `ContainerFormPage` pour la sélection d'équipements afin d'améliorer les performances. - Optimisation de `EquipmentSelectionDialog` avec chargement automatique des pages suivantes si les filtres réduisent trop la liste visible. - Passage à `withValues` pour la gestion des couleurs et amélioration de la gestion des erreurs et du logging.	2026-03-30 12:32:33 +02:00
ElPoyo	84c882ac0b	feat: Intégration d'un assistant IA logisticien basé sur Gemini - Ajout d'une Cloud Function `aiEquipmentProposal` utilisant le modèle Gemini avec function calling pour suggérer du matériel et des containers. - Implémentation de plusieurs outils (tools) côté serveur pour permettre à l'IA d'interagir avec Firestore : `search_equipment`, `check_availability_batch`, `get_past_events`, `search_event_reference` et `search_containers`. - Ajout de la dépendance `@google/generative-ai` dans le backend. - Création d'un service Flutter `AiEquipmentAssistantService` pour communiquer avec la nouvelle Cloud Function. - Ajout d'une interface de dialogue `AiEquipmentAssistantDialog` permettant aux utilisateurs de discuter avec l'IA pour affiner les propositions de matériel. - Intégration de l'assistant IA dans la section de gestion du matériel des événements (`EventAssignedEquipmentSection`). - Mise à jour de `DataService` avec de nouvelles méthodes de recherche et de vérification de disponibilité optimisées pour l'assistant. - Activation du mode développement et configuration des identifiants de test dans `env.dart`. - Optimisation des paramètres de la Cloud Function (timeout de 300s et 1GiB de RAM) pour supporter les traitements IA.	2026-03-24 12:00:30 +01:00
