FG Tracker is a production-ready real-time tracking and communication platform built with Flutter, Node.js, Socket.IO, WebRTC, and MySQL. Users can create or join tracking groups via QR code, monitor all member locations live on a map, search and find group members instantly, and communicate through single chat, group chat, and audio/video calls — all built from scratch with custom WebRTC and Socket.IO signaling.
