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);
     });
   }
