zebra_datawedge 0.1.1

Support hardware scanner for Zebra devices (ET5X).

zebra_datawedge

NOTICE: This package is forked from here to support for null-safety

Only for Android. Based on this example: https://github.com/darryncampbell/DataWedge-Intent-Example-1

This package was created to support hardware scanner for Zebra devices (ET5X) with older DataWedge Version (^5.0). Providing a simple stream which contains events fired by DataWedge (5.0).

For sure this is a minimal solution as it focus only to support DataWedge version 5.0. With never DataWedge versions there are more possibilities and also prettier solutions. Like creating incode the necessary profile.

Profile Configuration

As described in the previous written link, you have to set up your profile configuration properly to be able listen for the DataWedge Intent.

1. go to the DataWedge application and create a new profilefor our application or modify the Profile0.
2. Enable the profile
3. Enable Barcode input
4. Enable Intent output
5. Configure the Intent outputas follows:
   1. Intent action = io.mway.flutter_zebra_datawedge.ACTION
   2. leave Intent category empty
   3. Intent delivery = Broadcast

Example

  String _data = "waiting...";
  String _labelType = "waiting...";
  String _source = "waiting...";

  // create a listener for data wedge package
  Future<void> initDataWedgeListener() async {
    DataWedgeIntent.listenForDataWedgeEvent((response) {
      if (response != null && response is String)
        setState(() {
          Map<String, dynamic> jsonResponse;
          try {
            jsonResponse = json.decode(response);
          } catch (e) {
            //TODO handling
          }
          if (jsonResponse != null) {
            _data = jsonResponse["decodedData"];
            _labelType = jsonResponse["decodedLabelType"];
            _source = jsonResponse["decodedSource"];
          } else {
            _source = "An error occured";
          }
        });
    });
  }

Info

This package is only tested on Zebra ET5X with Android version 5.1.1 and DataWedge version 5.0.17.
