hid_monitor library

A cross-platform Flutter plugin for monitoring HID (Human Interface Device) events.

This plugin provides global keyboard and mouse event monitoring on Windows, macOS, and Linux platforms using FFI (Foreign Function Interface) to communicate with native libraries.

Features

• Keyboard event monitoring (key down/up)
• Mouse event monitoring (movement, buttons, scroll wheel)
• Cross-platform support (Windows, macOS, Linux)
• High-performance native library access

Getting Started

import 'package:hid_monitor/hid_monitor.dart';

void main() async {
  final backend = getListenerBackend();
  if (backend != null && backend.initialize()) {
    backend.addKeyboardListener((event) {
      print('Key event: $event');
    });
    backend.addMouseListener((event) {
      print('Mouse event: $event');
    });
  }
}
