Personal Finance & Portfolio Dashboard

Overview
Cross-platform Flutter app tracking daily expenses and live crypto/stock portfolio value via real-time public APIs.
The Challenge
Personal finance apps are either too complex (banking integrations) or too simple (basic calculators). A mid-tier solution is needed: expense tracking with live portfolio visualization, no bank linking required.
Our Solution
A Flutter app with Riverpod state management. Manual expense entry with category tagging. Live portfolio tracking via CoinGecko (crypto) and AlphaVantage (stocks) APIs. Beautiful fl_chart line graphs showing 30-day trends.
Technical Architecture
- Flutter App — Riverpod, GoRouter, fl_chart
- Data Feeds — CoinGecko API (crypto), AlphaVantage (stocks)
- Local Storage — Hive/SharedPreferences for offline expense data
- Charts — fl_chart for interactive line and pie charts
Results & Status
Architecture designed. UI mockups pending. Build scheduled after Graffiti App completion.
