uhf_c72_plugin_2 0.2.9

A flutter plugin for UHF C72 to read and write UHF Cards. Extended version.

uhf_c72_plugin_2

A better flutter plugin for UHF type C72 to read UHF Cards.

Getting Started

• Import the library:

  import 'package:uhf_c72_plugin/uhf_c72_plugin.dart';

• Open connection to the UHF reader

  await UhfPlugin.connect;

  Returns: bool? (nullable)

    @override
    void initState() {
       super.initState();
       initRFID();
    }
  
    void initRFID() async {
       await UhfC72Plugin.connect;
    }
  

• Check if is the reader connected

  await UhfC72Plugin.isConnected;

  Returns: bool? (nullable)

    @override
    void initState() {
       super.initState();
       initRFID();
    }
  
    void initRFID() async {
       await UhfC72Plugin.connect;
       await UhfC72Plugin.isConnected;
    }
  

• Start reading data from a single UHF card

  await UhfC72Plugin.startSingle;

  Returns: bool? (nullable)

• Start reading data multi 'continuous' UHF cards

  await UhfC72Plugin.startContinuous;

  Returns: bool? (nullable)

• Is started reading

  await UhfC72Plugin.isStarted;

  Returns: bool? (nullable)

• Write data to UHF card

  await UhfC72Plugin.writeData(int ptr, int len, String value);

  Takes: int ptr => Default: 2, int len => How many multiples of 4 ex: 2 => 2x4 = 8, String value => Any string that's length is a multiple of 4, len determines the number of characters written in the UHF card

  Returns: bool? (nullable)

• Read data to UHF card

  await UhfC72Plugin.readData(int ptr, int len);

  Returns: String? (nullable)

• Erase data from UHF card

  await UhfC72Plugin.eraseData(int ptr, int len);

  Returns: bool? (nullable)

• Stop Reading

  await UhfC72Plugin.stop;

  Returns: bool? (nullable)

• Close the connection

  await UhfC72Plugin.close;

  Returns: bool? (nullable)

• Clear cached data for the reader

  await UhfC72Plugin.clearData;

  Returns: bool? (nullable)

• Is Empty Tags

  await UhfC72Plugin.isEmptyTags;

  Returns: bool? (nullable)

• Set Power level (5 dBm : 30 dBm use string numbers)

  await UhfC72Plugin.setPowerLevel;

  Returns: bool? (nullable)

• Set Work Area Values { "1", "2", 4", "8", "22", "50", "51", "52", "128"}

  await UhfC72Plugin.setWorkArea;

  Returns: bool? (nullable)

• Listen to tags status

  UhfC72Plugin.tagsStatusStream.receiveBroadcastStream().listen(updateTags);

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