🎧 Inspiration We wanted to build a music player that wasn’t just another streaming clone. With Sonix, we envisioned an app that delivers rich, responsive audio experiences with sleek performance and personalization. Windsurf caught our eye for its powerful UI/UX components tailored for Flutter—it gave us the perfect wave to ride.

🚀 What it does Sonix is a modern music player that offers:

Smooth audio playback with waveform visualizations

Smart playlists curated by listening habits

Offline sync and local file management

Intuitive, minimal design powered by Windsurf widgets

Lightning-fast UI response and seamless navigation

🛠️ How we built it Frontend: Flutter (with Windsurf for beautiful UI components)

Audio Processing: Just Audio & AudioService packages

State Management: Riverpod

Storage: Hive for offline caching

Design: Figma prototypes translated into Flutter layouts with Windsurf support

🧗 Challenges we ran into Integrating audio background services without breaking UI flow

Syncing offline tracks with real-time visualization

Customizing Windsurf components to fit a music-first aesthetic

Managing device permissions across platforms

🏆 Accomplishments that we're proud of Built a fully functional, responsive music player in record time

Seamless offline + streaming experience

Leveraged Windsurf to deliver a crisp design without compromise

Optimized app for both Android and iOS in one codebase

📚 What we learned How to creatively extend Windsurf for media-heavy apps

Fine-tuning audio visualizations to sync with playback in real-time

Managing Flutter’s audio stack efficiently with low latency

Streamlining app performance across platforms and screen sizes

🔮 What's next for Sonix Adding voice control and gesture-based playback

Exploring AI-curated playlists using user moods and activity

Blockchain-based track ownership and royalty tagging
