The Scanbot SDK Flutter Plugin is available on pub.dev as the scanbot_sdk package. Follow the steps below to add it to your Flutter project.

Add the package​

Include the scanbot_sdk package in your pubspec.yaml file under dependencies:

dependencies:
  scanbot_sdk: ^5.1.0  # Use the latest version

Get the latest version from the Changelog.

Then, fetch and install the packages using the Flutter CLI or your IDE:

$ flutter pub get

Android​

In the top-level android/build.gradle file:

  • Ensure the Kotlin version is set to 1.8.22 or higher. Typically, this is defined using the ext.kotlin_version variable:

    ...
    buildscript {
        ext.kotlin_version = '1.8.22'
        ...
    }

  • Add the following packagingOptions

      android {
          ...
          packagingOptions {
              pickFirst 'META-INF/atomicfu.kotlin_module'
              pickFirst 'META-INF/proguard/coroutines.pro'
              exclude 'META-INF/LICENSE.txt'
              exclude 'META-INF/NOTICE.txt'
              exclude 'META-INF/LICENSE'
              exclude 'META-INF/NOTICE'
          }
      }

In the android/app/src/main/AndroidManifest.xml file, add the largeHeap flag: Since your application will work with high-resolution images it is strongly recommended to add the attribute android:largeHeap="true" in the <application> element of your AndroidManifest.xml file, especially for Android <= 7.x. Processing hi-res images is a memory intensive task and this property will ensure your app has enough heap allocated to avoid OutOfMemoryError exceptions.

iOS​

In your ios/Podfile, ensure a global platform version is specified:

platform :ios, '13.0'

Navigate to the ios directory and install or update the Pods:

$ cd ios/
$ pod install
