• Add it to the MauiProgram.cs

  var builder = MauiApp.CreateBuilder();
  builder
  .UseMauiApp<App>()
  .UseMauiCommunityToolkit()
  .ConfigureFonts(fonts => {
      fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
      fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
  });

• Add event in code behind for each button click and apply the below code.

  CommunityToolkit.Maui.Core.Platform.StatusBar.SetColor(statusBarColor);

Screen Design:

As a first point, we need to implement the screen design as per our requirement. In this tutorial, we will use 3 controls - 2 labels, and button like in the following code block.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:resource="clr-namespace:MauiLocalization"
             x:Class="MauiLocalization.MainPage">

            Spacing="25"
            Padding="30,0"
            VerticalOptions="Center">

            <Image
                Source="dotnet_bot.png"
                SemanticProperties.Description="Cute dot net bot waving hi to you!"
                HeightRequest="200"
                HorizontalOptions="Center" />

            <Label
                Text="{x:Static resource:LangResources.Helloworld}"
                SemanticProperties.HeadingLevel="Level1"
                FontSize="32"
                HorizontalOptions="Center" />

            <Label
                Text="{x:Static resource:LangResources.WelcomeNote}"
                SemanticProperties.HeadingLevel="Level2"
                SemanticProperties.Description="Welcome to dot net Multi platform App U I"
                FontSize="18"
                HorizontalOptions="Center" />

            <Button
                x:Name="CounterBtn"
                Text="Change to Tamil"
                SemanticProperties.Hint="Counts the number of times you click"
                Clicked="OnCounterClicked"
                HorizontalOptions="Center" />

        </VerticalStackLayout>
    </ScrollView>

</ContentPage>

Create RESX file

In this step, we will see the steps to create RESX file.

• In the Solution Explorer, right-click on the project or folder where you want to add the RESX file.
• Select "Add" from the context menu and then choose "New Item" or "New Folder" if you want to organize your resources in a separate folder.
• In the "Add New Item" dialog box, search for "Resource File" or navigate to "General" -> "Text File" and name the file with the .resx extension.
• Click the "Add" button to create the resource file.
• We created two resources file. One is default and another one prefixed with the language code.
  1. LangResources.resx
  2. LangResources.ta.resx (Contains the resource equivalent in tamil)

RESX Files in XAML

• To utilize your resources, you first need to import the XML namespace associated with them.

xmlns:resource="clr-namespace:MauiLocalization"

• Then, you can access your strings by using the [x:Static](https://learn.microsoft.com/en-us/xamarin/xamarin-forms/xaml/xaml-basics/xaml-markup-extensions#the-xstatic-markup-extension) markup extension, treating them as properties.

  Text="{x:Static resource:LangResources.Helloworld}"

Language Update

• Add click event to the button to change language based on the language code of the resource file.

  private void OnCounterClicked(object sender, EventArgs e)
  {
  	if (CounterBtn.Text.Contains("Tamil"))
  	{
  		LangResources.Culture = new CultureInfo("ta");
  		CounterBtn.Text = "Change to English";
  	}
  	else
  	{
  		LangResources.Culture = CultureInfo.InvariantCulture;
  		CounterBtn.Text = "Change to Tamil";
  	}
  	App.Current.MainPage = new MainPage();
  }

• Here, "App.Current.MainPage = new MainPage();" is used to refresh page once the language changed
• Then, we will add the below block in the page constructor to retain the language change once the button clicked and page refreshed.

  if (LangResources.Culture != null && LangResources.Culture.TwoLetterISOLanguageName.Contains("ta"))
  {
  	CounterBtn.Text = "Change to English";
  }
  else
  {
  	CounterBtn.Text = "Change to Tamil";
  }

Functional part

• Add a click event for the button to select the image like below.

private async void SelectBarcode(object sender, EventArgs e)
{
	var images = await FilePicker.Default.PickAsync(new PickOptions
	{
		PickerTitle = "Pick Barcode/QR Code Image",
		FileTypes = FilePickerFileType.Images
	});
	var imageSource = images.FullPath.ToString();
	barcodeImage.Source = imageSource;
	outputText.Text = imageSource;
}

Here,

• FileTypes: The default file types available for selection in the FilePicker are FilePickerFileType.Images, FilePickerFileType.Png, and FilePickerFileType.Videos. However, if you need to specify custom file types for a specific platform, you can create an instance of the FilePickerFileType class. This allows you to define the desired file types according to your requirements.
• PickerTitle: The PickOptions.PickerTitle is presented to the user and its behavior varies across different platforms.

• DrawView is a class provided by Community.Toolkit.Maui which is responsible for providing a surface that allows drawing lines through touch or mouse interaction.
• Add the following namespace in the xaml file.

  xmlns:mct="clr-namespace:CommunityToolkit.Maui.Views;assembly=CommunityToolkit.Maui"

• Once the namespace added, you have to add the DrawingView tag with the properties that we required like below.

  <mct:DrawingView x:Name="DrawBoard"
                      LineColor="Black"
                      LineWidth="5" 
                      HorizontalOptions="FillAndExpand"
                      VerticalOptions="FillAndExpand"
                      HeightRequest="250"
                      IsMultiLineModeEnabled="True"
                      DrawingLineCompleted="DrawBoard_DrawingLineCompleted"
                      BackgroundColor="AliceBlue"/>

DrawingView’s properties

• WidthRequest and HeightRequest: These properties help to set the width and height respectively.
  Keep in mind that you must add both properties to your DrawingView in order for it to be displayed correctly in your app.
• LineColor: It’s the color of the drawing line.
• LineWidth: It’s the width of the drawing line.
• IsMultiLineModeEnabled: By default, the DrawingView allows only one stroke to be drawn at a time. The IsMultiLineModeEnabled property allows you to change this and draw multiple lines at once. It receives Bool values. To activate it you need to set the value to True.

Cleaning the DrawView:

• If you want to clear the DrawView, add the following

  DrawBoard.Lines.Clear();

• The clear function can be called using the button click event and can be called like below

  <Button Text="Clear Board" 
                      Clicked="Button_Clicked"/>

  void Button_Clicked(System.Object sender, System.EventArgs e)
  {
  	DrawBoard.Lines.Clear();
  }

Previewing the signature or drawing from DrawView:

• Add an Image control to your XAML.

<Image x:Name="ImageView"
       WidthRequest="200"
       HeightRequest="200"/>

• Add an event for DrawingLineCompleted in the code behind.

private void DrawBoard_DrawingLineCompleted(System.Object sender, CommunityToolkit.Maui.Core.DrawingLineCompletedEventArgs e)
{
	ImageView.Dispatcher.Dispatch(async() =>
	{
		var stream = await DrawBoard.GetImageStream(300, 300);
		ImageView.Source = ImageSource.FromStream(() => stream);
	});
}

Install QRCoder nuGet package on your .NET MAUI application.

QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeData qrCodeData = qrGenerator.CreateQrCode(InputText.Text, QRCodeGenerator.ECCLevel.L);
PngByteQRCode qRCode = new PngByteQRCode(qrCodeData);
byte[] qrCodeBytes = qRCode.GetGraphic(20);
QrCodeImage.Source = ImageSource.FromStream(() => new MemoryStream(qrCodeBytes));

The above lines only need to generate the QR code for your mobile application.

How to change the color of your QR code

The GetGraphics-method has some more overloads. The first two enable you to set the color of the QR code graphic. One uses Color-class-types, the other HTML hex color notation.

//Set color by using Color-class types
Bitmap qrCodeImage = qrCode.GetGraphic(20, Color.DarkRed, Color.PaleGreen, true);

//Set color by using HTML hex color notation
Bitmap qrCodeImage = qrCode.GetGraphic(20, "#000ff0", "#0ff000");

.NET MAUI is a powerful platform for building cross-platform mobile applications, and with the right tools and resources, it's easy to add barcode scanning functionality to your app. In this tutorial, we'll walk you through the steps of implementing a barcode scanner in .NET MAUI using the ZXing.Net.MAUI plugin.

Project Setup:

• Launch Visual Studio 2022, and in the start window click Create a new project to create a new project.
  
• In the Create a new project window, select MAUI in the All project types drop-down, select the .NET MAUI App template, and click the Next button:
  
• In the configure your new project window, name your project, choose a suitable location for it, and click the Next button:
  
• In the Additional information window, click the Create button:
  
• Once the project is created, we can able to see the Android, iOS, Windows and other running options in the toolbar. Press the emulator or run button to build and run the app
  

Implementation:

The successor to ZXing.Net.Mobile: barcode scanning and generation for .NET MAUI applications. First, we need to add the ZXing.Net.MAUI library to our project as a dependency. To do this, open the NuGet Package Manager and search for "ZXing.Net.MAUI". Install the package in your .NET MAUI project.

Install ZXing.Net.MAUI

Install ZXing.Net.MAUI NuGet package on your .NET MAUI application. Make sure to initialize the plugin first in your MauiProgram.cs, see below

// Add the using to the top
using ZXing.Net.Maui;

// ... other code 

public static MauiApp Create()
{
    var builder = MauiApp.CreateBuilder();
    builder
    .UseMauiApp<App>()
    .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.

<uses-permission android:name="android.permission.CAMERA" />

iOS

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

<key>NSCameraUsageDescription</key>
<string>This app uses barcode scanning to...</string>

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.

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"

<zxing:CameraBarcodeReaderView
  x:Name="cameraBarcodeReaderView"
  BarcodesDetected="BarcodesDetected" />

Full Code of MainPage.xaml:

Configure Reader options

cameraBarcodeReaderView.Options = new BarcodeReaderOptions
{
  Formats = BarcodeFormats.OneDimensional,
  AutoRotate = true,
  Multiple = true
};

Toggle Torch

cameraBarcodeReaderView.IsTorchOn = !cameraBarcodeReaderView.IsTorchOn;

Flip between Rear/Front cameras

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

Handle detected barcode(s)

protected void BarcodesDetected(object sender, BarcodeDetectionEventArgs e)
{
  foreach (var barcode in e.Results)
    Console.WriteLine($"Barcodes: {barcode.Format} -> {barcode.Value}");
}
