A flutter plugin for barcode scanner that works on both iOS and Android. Provides functionality for scanning several formats of 1D and 2D barcodes.

It uses Zxing on Android and Zxing+Zbar on iOS to detect codes from PDF and Image files.

Example using app

Getting Started

Depend on it

Add this to your package's pubspec.yaml file:

  barcode_finder: latest version

Android Platform

API 21 is the minimum supported for Android.


Lets take a look at how to use BarcodeFinder to scan any PDF or image File using File Picker as a auxiliar plugin.

Future<String?> scanFile() async {
    // Used to pick a file from device storage
    final pickedFile = await FilePicker.platform.pickFiles();
    if (pickedFile != null) {
        final filePath = pickedFile.files.single.path;
        if (filePath != null) {
            return await BarcodeFinder.scanFile(path: path);

Make sure you are passing a valid and permissioned path to BarcodeFinder.scanFile, in the exemple above, the package FilePicker provides it for us.
