I used Flutter to build a cross-platform app for both Android and iOS. The core features include:

Advanced Billing Logic

AI-powered Speech-to-Text (using speech recognition plugins)

UPI QR Generation & Bill Sharing (WhatsApp/SMS)

GST Rate Calculator

PDF Invoice Generator

Multi-language Support using localization

📚 What I Learned This project helped me improve my skills in:

Flutter state management and UI design

Working with platform-specific integrations (e.g., speech, file storage, UPI APIs)

Real-world usability and accessibility (especially with language and UI design)

Efficient PDF handling and QR generation

🚧 Challenges Faced Fine-tuning the speech recognition accuracy for different accents

Ensuring smooth PDF generation and sharing across devices

Managing UPI payment flows within app permissions

Handling multi-language localization without breaking UI layout
