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

  barcode_finder: latest version

Usage

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
    FilePickerResult result = await FilePicker.platform.pickFiles();
    if(result != null) {
        String path = result.files.single.path;
        String barcode = await BarcodeFinder.scanFile(path: path);
        return barcode;
    } else {
        // User canceled the picker
        return null;
    }
}

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