This sample app demonstrates how to integrate the Scanbot Flutter barcode scanning library into your Flutter apps.
The Scanbot Barcode Scanner SDK is a simple and intuitive high-level Flutter plugin that allows you to integrate fast and reliable barcode scanning for both Android and iOS.
The SDK utilizes your device's camera, which can be freely switched. You can also apply various filters to narrow down the results by barcode type or content, with regex pattern support to ensure you only capture the specific barcodes relevant to your application.
It operates entirely offline on the user's mobile device and takes only 0.04 seconds per scan. Scans are accurate even under challenging conditions, including damaged, small, or distant barcodes and low-light backgrounds.
The SDK can be implemented into your Flutter project with just a few lines of code and comes with Ready-To-Use UI components.

The Scanbot Barcode Scanner SDK offers the following scan modes, which are available out of the box in our ready-to-use UI.
This is the Barcode Scanner SDK's default scanning mode. It is optimized for detecting a single barcode at a time and is easily configurable to your needs. You can show a confirmation screen after scanning the barcode.
The barcode scanner plugin can also be configured to scan multiple barcodes in succession (without closing the scanning interface every time), to capture multiple barcodes from the camera view at once, or to count the scanned items.
Given one or more barcodes, the SDK will visually highlight the barcode on the user's screen and scan the correct items for your users. It automatically selects the barcode with the right barcode value from your camera feed.

The Scanbot barcode scanning plugin includes an optional barcode Overlay for all scanning workflows. It provides real-time barcode highlighting, preview, and tap-to-select functionalities.
Recognized barcodes are highlighted with a customizable frame and text, clearly distinguishing scanned from unscanned items. This allows your users to select barcodes manually by tapping or instead rely on automatic selection.
The Scanbot SDK also offers barcode scanning support for still images, enabling barcode detection from JPG and other image files. It supports single-image and multi-image detection and returns a list with the recognized barcodes.
The Scanbot barcode scanner library supports all common 1D- and 2D barcodes, such as QR codes or Aztec Codes, as well as multiple postal symbologies, including:
| Barcode type | Barcode symbologies |
|---|---|
| 1D Barcodes | EAN, UPC, Code 128, GS1-128, Code 39, Codabar, ITF, Code 25, Code 32, Code 93, Code 11, MSI Plessey, Standard 2 of 5, IATA 2 of 5, Databar (RSS), GS1 Composite |
| 2D Barcodes | QR Codes, Micro QR Codes, Aztec Code, PDF417 Code, Data Matrix, GiroCode, GTIN Code, PPN Code, UDI Code, Royal Mail |
| Postal Symbologies | USPS Intelligent Mail (IMb), Royal Mail RM4SCC Barcode, Australia Post 4-State Customer Code, Japan Post 4-State Customer Code, KIX |
💡 Please visit our docs for a complete overview of the supported barcode symbologies.
The Scanbot Barcode Scanner SDK supports a variety of data parsers that extract structured information from 2D barcodes such as QR Codes and Data Matrix. These include parsers for documents such as driving licences (AAMVA), boarding passes, medical certificates, SEPA forms, Swiss QR codes and vCard business cards.
💡 Please refer to our documentation for a full list of supported data parsers.
