Compatibility

Compatibility has been tested with a Flutter version of 3.24.1 and Dart 3.5.1

Setup

Create Flutter project and add the Jumio Mobile SDK module to it.

flutter create MyProject

Add the Jumio Mobile SDK as a dependency to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter

  jumio_mobile_sdk_flutter: ^4.11.0

And install the dependency:

cd MyProject
flutter pub get
cd ios && pod install

Integration

iOS

1. Add the "NSCameraUsageDescription"-key to your Info.plist file.
2. Your app's deployment target must be at least iOS 11.0

NFC

Check out the NFC setup guide.

Digital Identity

Check out the Digital Identity setup guide.

Device Risk

To include Jumio's Device Risk functionality, you need to add pod Jumio/DeviceRisk to your Podfile.

Android

AndroidManifest
Open your AndroidManifest.xml file and change allowBackup to false.

<application
...
android:allowBackup="false">
</application>
...

Make sure your compileSdkVersion, minSdkVersion and buildToolsVersion are high enough.

android {
  minSdkVersion 21
  compileSdkVersion 33
  buildToolsVersion "32.0.0"
  ...
}

Enable MultiDex
Follow the Android developers guide here

android {
  ...
  defaultConfig {
    ...
    multiDexEnabled true
  }
}

Upgrade Gradle build tools
The plugin requires at least version 4.0.0 of the Android build tools. This transitively requires and upgrade of the Gradle wrapper to version 7 and an update to Java 11.

Upgrade build tools version to 7.3.0 in android/build.gradle:

buildscript {
  ...
  dependencies {
    ...
    classpath 'com.android.tools.build:gradle:7.3.0'
  }
}

Modify the Gradle Wrapper version in android/gradle.properties.

Proguard

For information on Android Proguard Rules concerning the Jumio SDK, please refer to our Android guides.

To enable analytic feedback and internal diagnostics, please make sure to include the line

-keep class io.flutter.embedding.android.FlutterActivity

to your Proguard Rules.

Usage

1. Import "jumiomobilesdk.dart"

import 'package:jumio_mobile_sdk_flutter/jumio_mobile_sdk_flutter.dart';

2. The SDKs can be initialized with the following call:

Jumio.init("AUTHORIZATION_TOKEN", "DATACENTER");

Datacenter can either be US, EU or SG.
For more information about how to obtain an AUTHORIZATION_TOKEN, please refer to our API Guide.

3. As soon as the SDK is initialized, the SDK is started by the following call.

Jumio.start();

Retrieving information

Scan results are returned from the startXXX() methods asynchronously. Await the returned values to get the results. Exceptions are thrown issues such as invalid credentials, missing API keys, permissions errors and such.

Customization

Android

JumioSDK Android appearance can be customized by overriding the custom theme AppThemeCustomJumio. An example customization of all values that can be found in the styles.xml of the DemoApp.

iOS

JumioSDK iOS appearance can be customized to your respective needs. You can customize each color based on the device's set appearance, for either Dark mode or Light mode, or you can set a single color for both appearances. Customization is optional and not required.

You can pass the following customization options at Jumio.start:

Local Models for JumioDocfinder

If you are using our JumioDocFinder module, you can download our encrypted models and add them to your bundle from here and here.

We recommend to download the files and add them to your project without changing their names (the same way you add Localization files). This will save two network requests on runtime to download these files.

iOS

You also need to copy those files to the "ios/Assets" folder for Flutter to recognize them.

Android

You need to copy those files to the assets folder of your Android project (Path: "app/src/main/assets/")

FAQ

Face help animation breaks on Android

If face help animation looks as expected in debug builds, but breaks in release builds, please make sure to include the following rule in your Proguard file:

-keep class androidx.constraintlayout.motion.widget.** { *; }

iOS Simulator shows a white-screen, when the Jumio SDK is started

The Jumio SDK does not support the iOS Simulator. Please run the Jumio SDK only on physical devices.

iOS Runs on Debug, Crashes on Release Build

This happens due to Xcode 13 introducing a new option to their App Store Distribution Options:

"Manage Version and Build Number" (see image below)

If checked, this option changes the version and build number of all content of your app to the overall application version, including third-party frameworks. This option is enabled by default. Please make sure to disable this option when archiving / exporting your application to the App Store. Otherwise, the Jumio SDK version check, which ensures all bundled frameworks are up to date, will fail.

Alternatively, it is also possible to set the key manageAppVersionAndBuildNumber in the exportOptions.plist to false:

<key>manageAppVersionAndBuildNumber</key>
<false/>

App Crash at Launch for iOS

If iOS application crashes immediately after launch and without additional information, but works fine for Android, please make sure the following lines have been added to your Podfile:

post_install do |installer|
    installer.pods_project.targets.each do |target|
      if ['iProov', 'DatadogRUM', 'DatadogCore', 'DatadogInternal'].include? target.name
        target.build_configurations.each do |config|
          config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
        end
      end
    end
end

If you are working with Xcode 15 and above, please make sure the following lines have been added to your Podfile:

post_install do |installer|
    installer.pods_project.targets.each do |target|
      if ['iProov', 'DatadogRUM', 'DatadogCore', 'DatadogInternal'].include? target.name
        target.build_configurations.each do |config|
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
        end
      end
    end
end

Please refer to iOS guide for more details.

iOS Localization

After installing Cocoapods, please localize your iOS application using the languages provided at the following path:
ios -> Pods -> Jumio -> Localization -> xx.lproj

Make sure your podfile is up to date and that new pod versions are installed properly so your Localizable files include new strings. For more information, please refer to our Changelog and Transition Guide.

Empty Country List for Android Release Build

If country list is empty for the Android release build, please make sure your app has the proper internet permissions. Without a working network connection, countries won't load in and the list will stay empty.

If necessary, please add android.permission.INTERNET permission to your AndroidManifest.xml file.

The standard Flutter template will not include this tag automatically, but still allows Internet access during development to enable communication between Flutter tools and a running app. For more information, please refer to the official Flutter documentation.
