Cross-platform 9-Ball scorekeeper
A Flutter/Dart casual match scorekeeper for 9-Ball with innings tracking, break tracking, undo support, and an AI trash talk generator powered by the Claude API.
The Problem
Keeping score during a casual billiards match means someone has to remember the count, or use a phone app that wasn't designed for pool. Most score apps are generic.
The Solution
A minimal, tap-to-score interface designed for billiards — split screen for two players, tap to score, long press to undo, track innings and who broke. The AI trash talk generator adds personality at match end.
Screenshots
Enter player names and race length before the match — defaults to Race to 7
Tap to score, hold to undo, track innings and break — Allen leading 6-3

Tech Stack
Cross-platform — one codebase for iOS, Android, and Windows
Flutter's language — familiar from company Shell App work

API key management via .env file
Key Engineering Decisions
Intentionally minimal — no accounts, no cloud, no history. Just score the match.
Soft lock after match complete — tapping after winner declared does nothing
Long press to undo — prevents accidental score increments
Race length as number input (1-20) not dropdown — handicapped races vary
