Flutter: Upload Files to Your VPS (Tutorial)

In this tutorial, we'll walk you through building a full-stack file upload system where a Flutter app uploads files to a VPS server, and also displays a list of uploaded files with previews.

✅ Features Covered:
- Upload any file (image, PDF, etc.) from Flutter to your VPS
- List and preview uploaded files
- Backend built using Flask
- Files stored directly in uploads/ folder
- Works with Android Studio emulator (10.0.2.2) or real device on same network

🔧 Technologies Used
- Flutter (Frontend mobile app)
- Http (for file upload in Flutter)
- Flask (Python backend)
- Gunicorn / Waitress (for production deployment)
- VPS (Linux or Windows with Python installed)

📁 Project Structure
Backend (Flask):
• /uploads folder to store files
• /upload API to receive file
• /files API to list uploaded files
• Static serving via Flask

Frontend (Flutter):
• File picker (using file_picker package)
• Upload button
• List view of files with download/view links (using url_launcher package)

🌍 Local Testing (Android Emulator)
Use http://10.0.2.2:5000 in your Flutter code to access the Flask server from emulator

🛡️ Deployment Tips
- Use Gunicorn or Waitress instead of flask run for production
- Enable firewall ports (5000 or 80)
- Use Nginx as a reverse proxy for SSL & performance (optional)
