Qr Renderer

Kuika's QR Renderer element is used to dynamically generate and display QR codes in your application. QR codes allow users to quickly scan and access specific data or a link. They are typically scanned by mobile devices and used to direct users to a specific page, share a link, or initiate a transaction. For example, you can display a QR code for a checkout page or event ticket. In this tutorial, you will learn how to create and display QR codes in your application using the QR Renderer element.

The QR Renderer element is only supported in web applications.

This training content consists of the following topics:

  • Add QR Renderer element
  • QR Renderer element properties
  • QR Code creation
  • QR Code display
  • QR Code scanning
  • Element settings and customization

Add Qr Renderer Element

  1. Log in to the Kuika platform.
  2. Select the project you will work on from the Apps screen.
  3. Enter the UI Design module.
  1. From the Elements panel on the left side, drag the QR Renderer element under the Display category and drop it on your screen.
  • If you drag the QR Renderer element to an empty space, it will automatically be added inside a Row element.
  • If you drag it into a Column, only the QR Renderer element is added.

Qr Renderer Element Properties

You can configure the properties of the QR Renderer element in the Properties panel on the right sidebar.

  • Value: Determines the data to be converted to QR code. You can enter a static value or dynamically retrieve the content of an Input element or the value obtained as a result of an action using Symbol Picker.

Creating and Reading Data with QR Code

QR code creation in Kuika is an effective way to improve the user experience in your app and make data more accessible. QR codes are often used in product tracking, user verification or mobile payment systems.

  • Data Encoding: You can provide fast information access by turning your data into QR codes. QR codes are created by converting string format data (e.g. text or URL) into base64 format and can be read via scanners or mobile devices.
  • Customization: QR codes can be integrated into your visual content. You can dynamically generate QR codes for different data and create codes specific to each user or product.
  • Performance: QR codes can be created and read quickly. By optimizing the data size, scanning speed can be increased and fast feedback can be provided when scanning with mobile devices.

QR Code Generation

The first step to create a QR code is to select the data you want to convert into a QR code. This data is usually kept in string format and is converted to base64 format during the QR code generation process. In this example, you will learn how to create a QR code using the URL element.

  1. Log in to the Kuika platform.
  2. Enter the UI Design module.
  1. Drag the URL element under the Text Input category from the Elements panel on the left side to the screen.
  1. In the Properties panel on the right side, enter the URL you want to convert into a QR code in the Value field.
  1. Choose On Change → Export → Generate QR Code from the ADD ACTION drop-down menu.
  1. In the Value field in the drop-down menu, click Symbol Picker and select Components → URL.

After these processes are completed, the QR code of the entered URL will be generated automatically.

QR Code Display

To display the QR code on a different screen, you can use the Navigate action to redirect to a new screen.

  1. To display the QR code on a different screen, click on the + icon from the Screens panel of the UI Design module.
  1. Select New Screen and name the screen "QR Code ”.
  1. Drag and drop the Image element under the Display category from the Elements panel on the left side.
  2. Go back to the screen where you added the Generate QR Code action.
  1. In the Properties panel on the right side, add the On Change → Navigation → Navigate action from the ADD ACTION drop-down menu.
  1. Select the "QR Code ” screen and the opening method from the To Screen field.
  2. Define the ID of the QR code by clicking on the Screen Input field on the right side.

Once this process is complete, your QR code will be displayed on the screen you just created.

QR Code Reading

Mobile devices and scanners can be used to scan QR codes. Simply add the Scan Barcode action to the element where you want to scan the QR code.

  1. Go back to the URL element.
  1. Add the On Change → Device → Scan Barcode action from the ADD ACTION drop-down menu.

This action allows users to scan the QR code via their mobile device or browser.
