+
+## Installation
+
+Install the latest version from [pub](https://pub.dartlang.org/packages/syncfusion_flutter_barcodes#-installing-tab-).
+
+## Getting started
+
+Import the following package.
+
+```dart
+import 'package:syncfusion_flutter_barcodes/barcodes.dart';
+```
+### Add Barcode Generator to the widget tree
+
+Add the Barcode Generator widget as a child of any widget. Here, the widget is added as a child of the container widget and the height to the container is specified (otherwise it will take full container height) 
+
+```dart
+ @override
+    Widget build(BuildContext context) {
+    return MaterialApp(
+      home: Scaffold(
+          body: Center(
+              child: Container(
+        height: 200,
+        child: SfBarcodeGenerator(value: 'www.syncfusion.com'),
+      ))),
+    );
+  }
+```
+## Add barcode symbology 
+
+Set the required symbology type to the barcode generator based on input value by initializing the **symbology** property. In the following code snippet, the QR code is set as the barcode symbology.
+
+```dart
+  @override
+  Widget build(BuildContext context) {
+    return MaterialApp(
+      home: Scaffold(
+          body: Center(
+              child: Container(
+        height: 200,
+        child: SfBarcodeGenerator(
+          value: 'www.syncfusion.com',
+          symbology: QRCode(),
+        ),
+      ))),
+    );
+  }
+```
+## Show value of the barcode
+
+input values can be displayed by enabling the **showValue** property of barcodes.
+
+```dart
+  @override
+  @override
+  Widget build(BuildContext context) {
+    return MaterialApp(
+      home: Scaffold(
+          body: Center(
+              child: Container(
+        height: 200,
+        child: SfBarcodeGenerator(
+          value: 'www.syncfusion.com',
+          symbology: QRCode(),
+          showValue: true,
+        ),
+      ))),
+    );
+  }
+```
+
+The following screenshot illustrates the result of the previous code sample.
