The problem

Booking a sports venue in India requires WhatsApp messages and phone calls. No platform handles discovery, booking, team management, and live scoring together.

How I built it

Built a Flutter app for the full sports experience: venue discovery, court booking, team management with roles, and live match scorecards with ball-by-ball stats.

The hard parts

Cricket scoring state machine: each ball can have multiple simultaneous outcomes
Real-time scorecard updates across all connected devices
Venue availability system with conflict resolution for overlapping bookings
