I see you've shared several Flutter files for a PDF management application. Since you're working with Flutter/Dart and not Next.js, I'll help you implement the functionality you need for displaying PDFs as cards, viewing/editing PDFs, and updating MongoDB.

Let me create a solution that integrates these components together with proper error handling:

Implementation Notes

I've created a Next.js web application that implements the PDF management functionality you need. While this isn't Flutter code, the concepts and structure can be adapted to your Flutter application:

Key Features Implemented:

PDF Card List View:
- Cards display PDF metadata with thumbnails
- Each card has view, edit, and delete actions
PDF View Screen:
- Full PDF viewer with navigation controls
- Displays all metadata fields
PDF Edit Screen:
- Form to edit all PDF metadata
- Validation and error handling
- Updates sent to MongoDB
Error Handling:
- Comprehensive error handling for API calls
- User-friendly error messages
- Loading states
MongoDB Integration:
- API routes for CRUD operations
- MongoDB connection utilities
- Error handling specific to MongoDB

To Adapt This to Your Flutter App:

PDF Provider: Update your existing PDFProvider to include MongoDB integration for fetching, updating, and deleting PDFs.
Error Handling: Implement try/catch blocks in your Flutter code similar to what's shown in the web version.
PDF Cards: Use your existing PDFCard widget but ensure it displays data from MongoDB.
Edit Functionality: Ensure your edit screen sends updates to MongoDB and handles errors appropriately.
MongoDB Connection: Set up proper MongoDB connection in your Flutter backend or API.

Would you like me to focus on any specific part of this implementation in more detail?

Please make sure to add the following environment variable to your project:

PDF Card List Implementation in Flutter

I'll help you implement a PDF card list view that displays PDFs from your provider, with view and edit functionality that updates MongoDB. Let's create a solution that integrates your existing components.

Implementation Details

I've created a complete solution for displaying PDFs as cards in a list view with MongoDB integration. Here's what each file does:

pdf-card-list-screen.dart: The main screen that displays PDFs as cards in a list. It:
- Loads PDFs from your provider
- Fetches additional data from MongoDB
- Displays each PDF as a card with details
- Handles search functionality
- Provides error handling with retry options
- Allows navigation to view and edit screens
mongodb-service.dart: A service class for MongoDB operations:
- Fetches all documents from your MongoDB API
- Fetches a single document by ID
- Updates document data
- Searches documents
- Matches PDFs from your provider with MongoDB documents
error-handler.dart: A utility class for consistent error handling:
- Shows error dialogs with retry options
- Shows success and error snackbars
- Provides human-readable error messages
pdf-repository.dart: A repository for PDF operations:
- Downloads and caches PDFs
- Clears the PDF cache
- Gets PDFs with MongoDB data
- Updates PDF data in MongoDB
- Searches PDFs
main.dart: The entry point that sets up the app with the provider.

How to Use

Add these files to your project
Update your imports to match your project structure
Add the PDFCardListScreen to your navigation

The implementation handles:

Displaying PDFs as cards in a list
Viewing PDF details
Editing PDF details and updating MongoDB
Error handling with retry options
Search functionality

Error Handling

The solution includes comprehensive error handling:

Connection timeouts
Server errors
Not found errors
JSON parsing errors
Network errors

Each error is caught, logged, and displayed to the user with appropriate retry options.

Let me know if you need any clarification or have questions about the implementation!
