scanwedge 0.0.1

A Flutter plugin to be able to work with the Zebra Datawedge

Scanwedge

Scanwedge is a Flutter plugin for Zebra devices with DataWedge to receive barcodes and create profiles It might support other devices later. This will only work on Android Zebra devices but it will not crash if used on other devices

Getting Started

Commands

Command	Description
createProfile	Created a new scanprofile, input is a ScanProfile that
enableScanner	Enables the scanner
disableScanner	Disables the scanner
suspendScanner	Suspends the scanner
resumeScanner	Resumes the scanner

Difference between enable/disable and suspend/resume is that enable/disable will work even if the scanner is ready but suspend/resume is much faster but will not work if scanner is not ready

Creating a new basic profile

final _scanwedgePlugin = Scanwedge();

//[profileName] will be the name of the profile, [packageName] is the packageName of the host application
final newProfile=ScanProfile(profileName: 'TestProfile', disableKeystroke: true, packageName: 'no.talgoe.scanwedge.scanwedge_example')
_scanwedgePlugin.createProfile(newProfile)

ScanProfile

This class can modify the profile that will be created

ScanProfile({
    required this.profileName,                      // The name of the profile
    this.configMode = ProfileCreateType.update,     // update, createIfNotExist, overwrite
    this.disableKeystroke = false,                  // disable sending scans to keyboard buffer
    this.barcodePlugin = BarcodePlugin(),           // See [BarcodePlugin]
    required this.packageName,                      // The packageName of your application.
});

BarcodePlugin

Possibility to set configuration related to barcode scanning. This will later have the possibility to enable/disable different barcodetypes

BarcodePlugin({
    this.aimType = AimType.trigger,             // See [AimType]
    this.timeoutBetweenScans = 0                // 0-5000 ms. Time between reading barcodes (for [AimType.presentation])
});

Listening for scan events

To receive the scan events you can listen to the Stream

final _scanwedgePlugin=ScanwedgeChannel();
@override build()=>Card(
    child: Column(
        mainAxisSize: MainAxisSize.min,
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
            const Text('Last scan:'),
            StreamBuilder(
                stream: _scanwedgePlugin.stream,
                builder: ((context, snapshot) => Text(
                        snapshot.hasData
                            ? snapshot.data.toString()
                            : snapshot.hasError
                                ? snapshot.error.toString()
                                : 'Scan something',
                        style: Theme.of(context).textTheme.titleMedium,
                    ))),
        ]
    )
);
