Usage

Library Pub link

https://pub.dev/packages/nordic_id

• Import the library:

import 'package:nordic_id/nordic_id.dart';
import 'package:nordic_id/tag_epc.dart';

• Initialize the Nordic ID reader await NordicId.initialize;

• Open connection to the Nordic ID reader await NordicId.connect

• Refresh and Start tracing/reading the ids/cards await NordicId.refreshTracing

• Stop tracing/reading the ids/cards await NordicId.stopTrace

• Is connected and can start tracing/reading the ids/cards bool? isConnected = await NordicId.isConnected

• Listen to connection status

   NordicId.connectionStatusStream
   .receiveBroadcastStream()
   .listen(updateConnection);
  
   bool isConnectedStatus = false;
   void updateConnection(dynamic result) {
   setState(() {
     isConnectedStatus = result;
   });
  }
  

  • Listen to tags status

  NordicId.tagsStatusStream
  .receiveBroadcastStream()
  .listen(updateTags);
  
  List<TagEpc> _data = [];
  void updateTags(dynamic result) {
      setState(() {
          _data = TagEpc.parseTags(result);
       });
     }
