flutter_honeywell_captuvo_plugin_nullsafe 1.0.0

Flutter wrapper for the Honeywell Captuvo SL22/42 iOS API with null safety.

Important: This package is based on the flutter_honeywell_captuvo_plugin that can be found at https://github.com/entegyopensource/flutter_honeywell_captuvo_plugin written by @entegyopensource.

The goal of this repository is to update the documentation for the project and to allow usage in flutter applications.

Flutter Honeywell Captuvo Plugin

Flutter wrapper for the Honeywell Captuvo SL22/42 iOS API with null safety.

Usage

Make sure you have the following added into the ios/Info.plist:

	<key>UISupportedExternalAccessoryProtocols</key>
	<array>
		<string>com.honeywell.scansled.protocol.decoder</string>
	</array>

There is only one main import that you should add into your dart files: import 'package:flutter_honeywell_captuvo_plugin/flutter_honeywell_captuvo_plugin.dart';

To use the SL22 or SL42 device we have to make sure we start it by calling: FlutterHoneywellCaptuvoPlugin.startDecoderHardware();

To get notified when the connection occurs we can use decoderConnectionStream here is a full example:

class _MyAppState extends State<MyApp> {
  StreamSubscription decoderConnectionStreamSubscription;

  @override
  void initState() {
    super.initState();
    FlutterHoneywellCaptuvoPlugin.startDecoderHardware();
    decoderConnectionStreamSubscription = FlutterHoneywellCaptuvoPlugin
        .decoderConnectionStream
        .listen((isConnected) {
      if (isConnected) {
        FlutterHoneywellCaptuvoPlugin.startDecoderHardware();
      }
    });
  }

  @override
  void dispose() {
    decoderConnectionStreamSubscription?.cancel();
    super.dispose();
  }
}

The last step is to get notified of barcode scanning changes:

class _MyAppState extends State<MyApp> {
  StreamSubscription decoderConnectionStreamSubscription;
  StreamSubscription decoderScanDataStreamSubscription;

  @override
  void initState() {
    super.initState();
    FlutterHoneywellCaptuvoPlugin.startDecoderHardware();
    decoderConnectionStreamSubscription = FlutterHoneywellCaptuvoPlugin
        .decoderConnectionStream
        .listen((isConnected) {
      if (isConnected) {
        FlutterHoneywellCaptuvoPlugin.startDecoderHardware();
      }
    });

    decoderScanDataStreamSubscription = FlutterHoneywellCaptuvoPlugin
        .decoderScanDataStream
        .listen((barcode) {
      print(barcode);
    });
  }

  @override
  void dispose() {
    decoderConnectionStreamSubscription?.cancel();
    decoderScanDataStreamSubscription?.cancel();
    super.dispose();
  }
}
