[Video] How to integrate Smile ID Flutter v7 SDK for Android

Gradle Integration

This is best done in Android Studio but if not installed can be done by looking at the android folder of your flutter native project

1. In your root-level (project-level) Gradle file (build.gradle), add rules to include the Maven Central repository.

buildscript {​    
        repositories {        
        mavenCentral() // add the maven central repository
         maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
          }
   }
}

2. Declare the Smile ID android SDK in your root level Gradle file (usually build.gradle).

dependencies {  
classpath group: 'com.smileidentity', name: 'smile-id-android', version: '1.0.1'
}

3. In your module (app-level) Gradle file (usually app/build.gradle), apply the Smile ID android plugin:

apply plugin: 'com.smileidentity.smile-id-android'

4. In your module (app-level) Gradle file (usually app/build.gradle), add the Smile ID UI and SDK dependancies

The latest version for smile id sdks can be found here

implementation 'com.smileidentity:smile-id-ui:<latest_version>'
implementation 'com.smileidentity:smile-id-sdk:<latest_version>'
implementation 'com.smileidentity:netjava:<latest_version>'// currently (0.0.8)

NB: If you have already integrated with the Android SDK only Remove the reference to the Smile ID dependency as the Smile UI will automatically pull the correct version in. and also remember to check the latest version here
