Ahoy, me hearties! Set sail on the high seas of image recognition with our Flutter plugin. Arrr! 🦜

🏴‍☠️ ar_quido 🏴‍☠️

Image recognition using Augmented Reality (AR) features for mobile Flutter apps. It uses EasyAR Sense on Android and native ARKit on iOS.

The plugin has been built by Flutter Division at Miquido Software development company.

Getting started 🚢

Add the dependency in your pubspec.yaml:

  • from command line:

    flutter pub add ar_quido
    flutter pub get
  • directly in pubspec.yaml:

       ar_quido: 0.2.0


Since the Android version depends on the EasyAR solution, you need to sign up on their page and obtain a "Sense Authorization" License Key. It can be done through the EasyAR Dashboard.

After doing so, provide the key in Android Manifest file as application's metadata:

           android:value="<YOUR_SENSE_LICENSE_KEY>" />


By default, proguard removes the EasyAR library files from a release build. To fix this, add the following code to the android/app/src/proguard-rules.pro file (create the file if it doesn't exist):

-keep class cn.easyar.** { *; }
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception


ARKit uses the device camera, so do not forget to provide the NSCameraUsageDescription in Info.plist:

<string>Describe why your app needs camera (AR) here.</string>

Also make sure, that your deployment target in project settings is set to at least 14.0. Set the same version in ios/Podfile:

platform :ios, '15.0'

Usage 🌴

  1. Put your reference images inside assets/reference_images directory (make sure to reference them in pubspec.yaml).

    • please note, that only .jpg images are supported at this time
  2. Place ARQuidoView widget in your view's code. Provide at least an array of image names you want to detect (through referenceImageNames property) and a callback for detected images (through onImageDetected property):

       referenceImageNames: const ['applandroid'],
       onImageDetected: (imageName) {
         // handle detected image
  3. That's it, you're all set ⚓

Please see the example for more info. You can also check the details in API Documentation.
