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
    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.
