The Syncfusion® Flutter Barcode Generator is a data visualization widget that generate and display data in a machine-readable format. It provides an efficient approach to encode text using supported symbology types.

Follow these instructions to implement the barcode generator in your Flutter application:

Step 1: Create a simple project using the instructions given in the Getting Started with your first Flutter app documentation.

Step 2: Add the Syncfusion® Flutter Barcode dependency to your pubspec.yaml file.

dependencies:
 
    syncfusion_flutter_barcodes: ^xx.x.xx
 

 Replace xx.x.xx with the current version of the Syncfusion® Flutter Barcodes package.

Step 3: Run the following command to fetch the required packages.

$ flutter pub get

Step 4: Import the following package in your Dart code.

Step 5: Add the Barcode Generator widget as a child of any widget. In this example, the widget is added as a child of a Container widget with a specified height (otherwise, it would take the full container height). The default symbology of SfBarcodeGenerator is Code128.

@override
    Widget build(BuildContext context) {
        return MaterialApp(
            home: Scaffold(
                body: Center(
                    child: Container(
                         height: 150,
                        child:SfBarcodeGenerator(value:'http://www.syncfusion.com')
                        )
                    )
                )      
            );
