Introduction

This plugin enables communication between Huawei ML SDK and Flutter platform. It allows your apps to easily leverage Huawei's long-term proven expertise in machine learning to support diverse artificial intelligence (AI) applications throughout a wide range of industries. Thanks to Huawei's technology accumulation, ML Kit provides diversified leading machine learning capabilities that are easy to use, helping you develop various AI apps.

Installation Guide

• Before you get started, you must register as a HUAWEI developer and complete identity verification on the HUAWEI Developer website. For details, please refer to Register a HUAWEI ID.

• Create an app by referring to Creating an AppGallery Connect Project and Adding an App to the Project.

• The data storage location determines the region where your app will connect to on-cloud services of ML Kit. To set the data storage location, go to Project Setting > General Information, click Set next to Data storage location under Project, and select a data storage location in the displayed dialog box. For details, please refer to Setting a Data Storage Location.

• A signing certificate fingerprint is used to verify the authenticity of an app when it attempts to access an HMS Core (APK) through the HMS SDK. Before using the HMS Core (APK), you must locally generate a signing certificate fingerprint and configure it in AppGallery Connect. For details, please refer to Generating a Signing Certificate.

• Sign in to AppGallery Connect and select My projects. After selecting your project, on the Project Setting page, set SHA-256 certificate fingerprint to the SHA-256 fingerprint. For details, please refer to Adding Fingerprint Certificate to AppGallery Connect.

• In AppGallery Connect, on My projects page, find your project from the list and select it. Go to Project Settings > General Information > App information. Click agconnect-service.json to download configuration file.

• Copy the agconnect-service.json file to the android/app directory of your project.

• Open the build.gradle file in the android directory of your project.

  • Go to buildscript then configure the Maven repository address and agconnect plugin for the HMS SDK.

    buildscript {
        repositories {
            google()
            jcenter()
            maven { url 'https://developer.huawei.com/repo/' }
        }
    
        dependencies {
            /*
             * <Other dependencies>
             */
            classpath 'com.huawei.agconnect:agcp:1.3.1.300'
        }
    }
    

  • Go to allprojects then configure the Maven repository address for the HMS SDK.

    allprojects {
        repositories {
            google()
            jcenter()
            maven { url 'https://developer.huawei.com/repo/' }
        }
    }
    

• Open the build.gradle file in the android/app directory.

  • Add apply plugin: 'com.huawei.agconnect' line after the apply plugin: 'com.android.application' line.

    apply plugin: 'com.android.application'
    apply plugin: 'com.huawei.agconnect'
    apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
    

  • Set your package name in defaultConfig > applicationId and set minSdkVersion to 19 or higher. Package name must match with the package_name entry in agconnect-services.json file.

    defaultConfig {
            applicationId "<package_name>"
            minSdkVersion 19
            /*
             * <Other configurations>
             */
        }
    

  • Copy the signature file that generated in Generating a Signing Certificate to android/app directory.

  • Configure the signature in android according to the signature file information.

    android {
        /*
         * <Other configurations>
         */
    
        signingConfigs {
            config {
                storeFile file('<keystore_file>.jks')
                storePassword '<keystore_password>'
                keyAlias '<key_alias>'
                keyPassword '<key_password>'
            }
        }
    
        buildTypes {
            debug {
                signingConfig signingConfigs.config
            }
            release {
                signingConfig signingConfigs.config
                minifyEnabled true
                shrinkResources true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    

• On your Flutter project directory find and open your pubspec.yaml file and add library to dependencies to download the package from pub.dev.

  dependencies:
      huawei_ml: {library version}
  

  or

  if you downloaded the package from the HUAWEI Developer website, specify the library path on your local device.

  dependencies:
      huawei_ml:
          # Replace {library path} with actual library path of Huawei ML Kit Flutter Plugin.
          path: {library path}
  

• Run following command to update package info.

  [project_path]> flutter pub get
  

• Run following command to start the app.

  [project_path]> flutter run
