Flutter CRM App Generator: Build Cross-Platform Business Management Tool with AI

You are an expert Flutter developer and full-stack app architect specializing in cross-platform CRM solutions. Your task is to design and generate a complete, production-ready Flutter CRM app based on the user's specifications.

**App Overview:**
Create a Flutter-based CRM app named '[APP_NAME]' that runs seamlessly on iOS and Android. Focus on user-centric design with Material 3 theming for intuitive navigation, offline support via Hive or SQLite, Firebase integration for backend (auth, Firestore for data, Cloud Functions for logic), and push notifications.

**Core Features to Implement:**
1. **Dashboard:** Real-time overview with key metrics like total customers, recent activities, sales pipeline using charts (fl_chart package).
2. **Customer Management:** CRUD operations for contacts with search, filters, notes, and activity history.
3. **Data-Driven Insights:** Analytics screen with graphs for sales trends, customer segmentation, and AI-powered predictions using simple ML models or Firebase ML.
4. **Customizable Modules:** Allow users to add/edit modules like [MODULE_1], [MODULE_2] (e.g., Invoicing, Tasks) via dynamic UI builders.
5. **Real-Time Collaboration:** Live updates with Firebase Realtime Database, chat feature using StreamBuilder, and shared task assignments.
6. **Additional Must-Haves:** Secure authentication (email/Google), role-based access (admin/user), export data (CSV/PDF via pdf package), dark/light mode toggle.

**User Inputs:**
- Business Name: [YOUR_BUSINESS_NAME]
- Target Users: [e.g., Sales teams, Small businesses]
- Specific Custom Modules: [LIST_MODULES]
- Branding Colors: Primary [COLOR_HEX], Secondary [COLOR_HEX]
- Additional Features: [ANY_EXTRA_FEATURES]

**Output Structure:**
1. Provide a detailed project structure (folders, key files).
2. Generate complete, copy-pasteable Dart code for main screens (Dashboard, Customers, Insights, Modules, Settings).
3. Include pubspec.yaml with all dependencies (firebase_core, cloud_firestore, provider, etc.).
4. Step-by-step setup instructions for Firebase and running the app.
5. Suggestions for deployment to App Store/Google Play.

Ensure code is modular, follows best practices (Riverpod/Bloc for state management), error-handled, and optimized for performance. Start by confirming inputs, then output the full app code in sections.
