# ZXing.Net.MAUI

The successor to ZXing.Net.Mobile: barcode scanning and generation for .NET MAUI applications



## Barcode Scanning

### Install ZXing.Net.MAUI

1. Install [ZXing.Net.Maui.Controls](https://www.nuget.org/packages/ZXing.Net.Maui.Controls) NuGet package on your .NET MAUI application

1. Make sure to initialize the plugin first in your `MauiProgram.cs`, see below

    ```csharp

    // Add the using to the top

    using ZXing.Net.Maui;

    

    // ... other code 

    

    public static MauiApp Create()

    {

    	var builder = MauiApp.CreateBuilder();

    

    	builder

    		.UseMauiApp()

    		.UseBarcodeReader(); // Make sure to add this line

    

    	return builder.Build();

    }

    ```

Now we just need to add the right permissions to our app metadata. Find below how to do that for each platform.

#### Android

For Android go to your `AndroidManifest.xml` file (under the Platforms\Android folder) and add the following permissions inside of the `manifest` node:

```xml

```

#### iOS

For iOS go to your `info.plist` file (under the Platforms\iOS folder) and add the following permissions inside of the `dict` node:

```xml

NSCameraUsageDescription

This app uses barcode scanning to...

```

Make sure that you enter a clear and valid reason for your app to access the camera. This description will be shown to the user.

#### Windows

Windows is not supported at this time for barcode scanning. You can however use the barcode generation. No extra permissions are required for that.

For more information on permissions, see the [Microsoft Docs](https://docs.microsoft.com/dotnet/maui/platform-integration/appmodel/permissions).

### Using ZXing.Net.Maui

If you're using the controls from XAML, make sure to add the right XML namespace in the root of your file, e.g: `xmlns:zxing="clr-namespace:ZXing.Net.Maui.Controls;assembly=ZXing.Net.MAUI.Controls"`

```xaml

```

Configure Reader options

```csharp

cameraBarcodeReaderView.Options = new BarcodeReaderOptions

{

  Formats = BarcodeFormats.OneDimensional,

  AutoRotate = true,

  Multiple = true

};

```

Toggle Torch

```csharp

cameraBarcodeReaderView.IsTorchOn = !cameraBarcodeReaderView.IsTorchOn;

```

Flip between Rear/Front cameras

```csharp

cameraBarcodeReaderView.CameraLocation

  = cameraBarcodeReaderView.CameraLocation == CameraLocation.Rear ? CameraLocation.Front : CameraLocation.Rear;

```

Handle detected barcode(s)

```csharp

protected void BarcodesDetected(object sender, BarcodeDetectionEventArgs e)

{

  foreach (var barcode in e.Results)

    Console.WriteLine($"Barcodes: {barcode.Format} -> {barcode.Value}");

}

```

## Barcode Generator View

```xaml

```
