Light Module

Control LED indicator lights on iMin POS devices.

Installation

Add to your pubspec.yaml:

dependencies:
  imin_hardware_plugin: ^1.0.0

Then run:

flutter pub get

Import

import 'package:imin_hardware_plugin/imin_hardware_plugin.dart';

The plugin exports IminLight class for LED light control.

Features

• Connect/disconnect to light device
• Turn on green light
• Turn on red light
• Turn off lights

API Reference

Connect to Device

bool success = await IminLight.connect();

Turn On Green Light

bool success = await IminLight.turnOnGreen();

Turn On Red Light

bool success = await IminLight.turnOnRed();

Turn Off Light

bool success = await IminLight.turnOff();

Disconnect from Device

bool success = await IminLight.disconnect();

Example

import 'package:imin_hardware_plugin/imin_hardware_plugin.dart';

class LightExample extends StatefulWidget {
  @override
  _LightExampleState createState() => _LightExampleState();
}

class _LightExampleState extends State<LightExample> {
  bool _isConnected = false;
  LightColor _currentLight = LightColor.off;

  Future<void> _connect() async {
    final success = await IminLight.connect();
    setState(() => _isConnected = success);
  }

  Future<void> _turnOnGreen() async {
    final success = await IminLight.turnOnGreen();
    if (success) {
      setState(() => _currentLight = LightColor.green);
    }
  }

  Future<void> _turnOnRed() async {
    final success = await IminLight.turnOnRed();
    if (success) {
      setState(() => _currentLight = LightColor.red);
    }
  }

  Future<void> _turnOff() async {
    final success = await IminLight.turnOff();
    if (success) {
      setState(() => _currentLight = LightColor.off);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Text('Connected: $_isConnected'),
        Text('Current: $_currentLight'),
        ElevatedButton(
          onPressed: _isConnected ? null : _connect,
          child: Text('Connect'),
        ),
        ElevatedButton(
          onPressed: _isConnected ? _turnOnGreen : null,
          child: Text('Green Light'),
        ),
        ElevatedButton(
          onPressed: _isConnected ? _turnOnRed : null,
          child: Text('Red Light'),
        ),
        ElevatedButton(
          onPressed: _isConnected ? _turnOff : null,
          child: Text('Turn Off'),
        ),
      ],
    );
  }
}

enum LightColor { off, green, red }

Notes

• Must connect to device before controlling lights
• Only one light can be active at a time
• Disconnect when done to free resources
