Draw, doodle, and create freely — your canvas, your rules
Draw it is a real-time collaborative canvas application developed using Flutter for the frontend and Node.js + Express with WebSocket for backend synchronization. The app allows multiple users to draw simultaneously on a shared board, demonstrating expertise in both cross-platform UI development and real-time network communication. 🚀 Key Objective: Enable seamless, real-time collaboration on a shared drawing board using a performant, event-driven architecture. 🧱 Tech Stack: Flutter (Dart): Cross-platform mobile frontend with gesture handling and custom rendering Node.js + Express.js: Backend server with WebSocket support for persistent bi-directional communication WebSocket (ws): For real-time synchronization of strokes across users CustomPainter: Efficient frame-by-frame drawing on canvas Permission Handler & RepaintBoundary: Save drawings as images on device 🖌️ Core Features: ✍️ Shared Real-Time Drawing: All participants see each other's strokes instantly using WebSocket broadcast. 📡 Stateless WebSocket Server: Lightweight Node.js server maintains active socket connections and relays stroke events with low latency. 🎨 Canvas Engine: Touch gestures are converted into drawable vector paths and rendered using Flutter's CustomPainter. 📁 Export Canvas: Users can save their artwork as an image 🔧 Modular Architecture: Separate layers for drawing logic, server events, and platform integration.
