Genius Scan SDK for Flutter


This Flutter plugin allows you to access the Genius Scan SDK core features from a Flutter application. The plugin relies on the ScanFlow module which provides a all-in-one scanner module with simple configurable input.

  • Automatic document detection
  • Document perspective correction
  • Image enhancement with 4 different modes (Black & white, Monochrome, Color, Photo)
  • Batch scanning of several pages in row
  • OCR to extract raw text from images and generate PDF with invisible text layer


This plugin is based on the Genius Scan SDK for which you need to setup a license. You can aleady try the "demo" version for free by not setting a license key, the only limitation being that the app will exit after 60 seconds.

To buy a license:

  1. Sign up to our developer console
  2. Submit a quote request for each application

You can learn more about licensing in our website and contact us at for further questions.

Getting started

Follow the install steps from

Additional steps on Android

  • To your app android/app/build.gradle, change minSdkVersion to 21.

Additional steps on iOS

  • Add the required permission to your Info.plist:
NSCameraUsageDescription - "We use the camera for <provide a good reason why you are using the camera>"
  • In your Podfile, add the following line:
platform :ios, '13.0'


Set the license key

Initialize the SDK with a valid license key:


This method doesn't return anything. However, other methods of the plugin will fail if the license key is invalid or expired. Note that, for testing purpose, you can also use the plugin without setting a license key, but it will only work for 60 seconds.

It is recommended to show a message to users asking them to update the application in case the license has expired.

Start the scanner module

var result = await FlutterGeniusScan.scanWithConfiguration(configuration);

See the API doc for the options supported in the configuration object and for the result structure.

(Optional) Generate a PDF document from multiple pages

If you'd like to rearrange the pages returned by the ScanFlow or add some more pages, you can do so and generate a PDF document from these pages:

await FlutterGeniusScan.generateDocument(configuration)

See the API doc for the options supported in the configuration object.


How do I get the UI translated to another language?

The device's locale determines the languages used by the plugin for all strings: user guidance, menus, dialogsā€¦

The plugin supports a wide variety of languages: English (default), Arabic, Chinese (Simplified), Chinese (Traditional), Danish, Dutch, French, German, Hebrew, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, Spanish, Swedish, Turkish, Vietnamese.

NB: iOS applications must be localized in XCode by adding each language to the project.

What should I do if my license is invalid?

Make sure that the license key is correct, that is has not expired, and that it is used with the App ID it was generated for. To learn more about the procurement and replacement of license keys, refer to the Licensing FAQ.
