v1
please add for the flash screen

Here's the updated code for the splash screen with a more polished design and animation:

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import '../providers/auth_provider.dart';

class SplashScreen extends StatefulWidget {
  const SplashScreen({Key? key}) : super(key: key);

  @override
  State<SplashScreen> createState() => _SplashScreenState();
}

class _SplashScreenState extends State<SplashScreen> with SingleTickerProviderStateMixin {
  late AnimationController _controller;
  late Animation<double> _animation;

  @override
  void initState() {
    super.initState();
    _controller = AnimationController(
      duration: const Duration(milliseconds: 1500),
      vsync: this,
    )..repeat(reverse: true);
    _animation = CurvedAnimation(
      parent: _controller,
      curve: Curves.easeInOut,
    );

    _checkAuthStatus();
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  Future<void> _checkAuthStatus() async {
    await Future.delayed(const Duration(seconds: 2));
    final authProvider = Provider.of<AuthProvider>(context, listen: false);
    if (authProvider.user != null) {
      if (authProvider.user?.role == 'admin') {
        Navigator.pushReplacementNamed(context, '/admin/dashboard');
      } else {
        Navigator.pushReplacementNamed(context, '/user/home');
      }
    } else {
      Navigator.pushReplacementNamed(context, '/login');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Theme.of(context).primaryColor,
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ScaleTransition(
              scale: _animation,
              child: Image.asset(
                'assets/logo.png',
                width: 150,
                height: 150,
                color: Colors.white,
              ),
            ),
            const SizedBox(height: 20),
            FadeTransition(
              opacity: _animation,
              child: Text(
                'Delivery App',
                style: TextStyle(
                  fontSize: 24,
                  fontWeight: FontWeight.bold,
                  color: Colors.white,
                ),
              ),
            ),
            const SizedBox(height: 20),
            CircularProgressIndicator(
              valueColor: AlwaysStoppedAnimation<Color>(Colors.white),
            ),
          ],
        ),
      ),
    );
  }
}

To use this splash screen, you'll need to:

  1. Add a logo image to your assets folder (e.g., assets/logo.png)
  2. Update your pubspec.yaml to include the asset:
flutter:
  assets:
    - assets/logo.png
  1. Update your main app to use this splash screen as the initial route:
void main() {
  runApp(
    MaterialApp(
      title: 'Delivery App',
      theme: ThemeData.light(),
      darkTheme: ThemeData.dark(),
      home: SplashScreen(),
      debugShowCheckedModeBanner: false,
    ),
  );
}

This splash screen includes:

  • A scaling animation for the logo
  • A fade-in animation for the app name
  • A loading indicator
  • Automatic navigation to the appropriate screen based on auth status
  • A clean, modern design with your app's theme colors

The splash screen will:

  1. Show for 2 seconds
  2. Check if the user is logged in
  3. Redirect to the appropriate screen (admin dashboard, user home, or login) based on auth status_
please can you add for the 3d ui this app

Here's how to enhance your delivery app with 3D UI elements using Flutter's flutter_3d_controller package and other visual improvements:

Implementation Notes:

  1. Required 3D Models:

    • Create an assets/3d_models/ folder and add:
      • delivery_box.obj - For the package visualization
      • product1.obj, product2.obj, product3.obj - Sample products
      • map.obj - For the tracking screen
      • delivery_truck.obj - For the delivery vehicle
  2. Key 3D Features Added:

    • Interactive 3D product viewer with rotation control
    • Animated delivery box on the order screen
    • 3D order tracking visualization with moving delivery truck
    • Smooth animations for all 3D elements
  3. Integration Points:

    • Replace product images with 3D models in the order flow
    • Enhanced order tracking with 3D map visualization
    • Interactive elements that respond to user gestures
  4. Performance Considerations:

    • Use optimized 3D models (low poly count)
    • Implement loading states for 3D assets
    • Consider using Visibility widgets to unload 3D elements when not visible

To complete the setup:

  1. Add the 3D model files to your assets folder
  2. Run flutter pub get to install dependencies
  3. Update your app's navigation to include the new 3D screens

The 3D elements will make your delivery app more immersive while maintaining all the existing functionality._

v2
can you add for the database

Here's the comprehensive database implementation for your Flutter delivery app with Firebase Firestore, including models, services, and security rules:

Key Database Features Implemented:

  1. Firestore Structure:

    • users collection: Stores user profiles with role-based access
    • orders collection: Tracks all delivery orders with status history
  2. Security Rules:

    • Users can only access their own profile
    • Role-based order access (users see their orders, admins see all)
    • Validation for order status transitions
  3. Optimized Queries:

    • Composite indexes for efficient order queries
    • Real-time updates using Firestore streams
  4. Data Models:

    • Enhanced UserModel with additional profile fields
    • Comprehensive OrderModel with tracking information
  5. State Management:

    • Integrated with Provider for reactive UI updates
    • Separate OrderProvider for order-related state

Implementation Steps:

  1. Add these files to your project
  2. Deploy the Firestore rules (firestore.rules)
  3. Create the indexes (firestore.indexes.json)
  4. Initialize Firebase in your app
  5. Use the providers in your widgets for data access

The database is now set up with:

  • Proper security rules
  • Optimized queries
  • Real-time updates
  • Comprehensive data models
  • Clean separation of concerns

All database operations are handled through the service classes, making it easy to maintain and test.

Updated files
v3
can you add for the admin dashboard and overview

Here's the comprehensive implementation for the admin dashboard with analytics and overview features:

Key Features of the Admin Dashboard:

  1. Real-time Analytics Dashboard:

    • Shows today's orders, pending orders, and total revenue
    • Updates automatically with Firestore real-time updates
  2. Visual Data Representation:

    • Pie chart showing order status distribution
    • Color-coded status indicators
    • Responsive design for all screen sizes
  3. Recent Orders Table:

    • Displays last 5 orders with key details
    • Sortable columns (implement sorting logic as needed)
    • Horizontal scroll for smaller devices
  4. Performance Optimizations:

    • Efficient data queries with Firestore indexes
    • Minimal widget rebuilds using Provider
    • Pagination for large order lists (can be added)
  5. Additional Features Ready:

    • Refresh button to manually update data
    • Color-coded status indicators
    • Formatted currency and dates

Implementation Notes:

  1. Add charts_flutter to your pubspec.yaml
  2. The dashboard automatically connects to your existing Firestore database
  3. All widgets are reusable and can be placed in other admin screens
  4. The design follows Material Design guidelines

For a complete admin panel, you can expand this with:

  • User management screen
  • Detailed order analytics
  • Driver assignment interface
  • Revenue reports by date range

The dashboard provides admins with immediate visibility into the delivery operations with minimal loading times thanks to Firestore's real-time capabilities._
