Firelink

Firelink is a high-performance, visually stunning Network Topology Simulation and Configuration tool built entirely with Flutter. Designed for both students learning networking concepts and professionals visualizing architectures, Firelink allows you to dynamically build, configure, and simulate complex network interactions right on your device.

Features

• Infinite Workspace Canvas: Drag and drop devices, draw connections, and arrange your architecture on a hardware-accelerated infinite panning and zooming grid.
• Comprehensive Device Configuration:
  • Manage IPv4 addresses, Subnet Masks, Default Gateways, and DNS servers per interface.
  • Configure Hostnames, Static Routing Tables, and Access Control Lists (ACLs).
• Packet Simulation (PDU):
  • Simple PDU: Quickly test reachability between two nodes.
  • Complex PDU: Construct detailed custom packets (custom TTL, specific source/destination IPs) and watch their animated journey across your topology.
• Campaign / Tutorial Mode: Interactive built-in lessons (Level 1 to Level 5) designed to teach networking basics, from linking simple devices to configuring routers and DHCP servers.
• Project Persistence: Save your topology locally as .firelink files and load them up later instantly using Isolate-based background parsing.
• Bilingual & Theming: Full support for Dark/Light mode and bilingual localization (English & Bahasa Indonesia).
• Ultra-Optimized Performance: Built without heavy RepaintBoundary wrappers, rendering hundreds of devices at a buttery smooth 60 FPS using raw Matrix Inversion and PointMode algorithms.
