Unity-Flutter-echoAR-example

Starter project to build Android apps using Flutter & Unity with echoAR

Register

Make sure you have an echoAR API key. If you don't have one yet, register for FREE at echoAR.

Setup

• Add a 3D model to the console.
• Create a new Unity project.
• Install the echoAR Unity SDK.
• Open the sample scence under echoAR/Examples/sample.unity.
• Set the API key in the Inspector of the echoAR game object.

Unity project build settings

NOTE: The flutter plugin we use in this example currently has no support for iOS. If you wish to build for iOS you can try using another 3rd party plugin. The following building instructions are for Android build. The Run section of this guide is applicable for both iOS and Android

• Open the Build Settings window by clicking File > Build Settings....
• Select Android and click Switch Platform.
• Check Export Project
• Open the Player Settings window by clicking Player Settings...
• Configure the folowing:
  • Other Settings > Rendering > Graphics APIs: OpenGLES3
  • Other Settings > Configuration > Scripting Backends: IL2CPP
  • Other Settings > Configuration > Target Architectures: ✔ ARMv7, ✔ ARM64
• Notice what is your Minimum API Level. You may need it later.
• Close the Player Settings window
• Click Add Open Scenes
• Click Export and save as unityExport

Flutter configuration

• Import the project dependecies by running flutter pub get from your terminal
• Copy the unityExport folder to <your_flutter_project>/android/unityExport
• Run flutter pub run flutter_unity:unity_export_transmogrify in your terminal
• Open <your_flutter_project>/android/app/build.gradle and make sure your project minSdkVersion equals to the one you defined for your Unity Project as Minimum API Level.
• Open <your_flutter_project>/android/build.gradle and, inside allprojects { repositories {} }, add the following:

  flatDir {
      dirs "${project(':unityExport').projectDir}/libs"
  }
  

  so it will look something like this:

          allprojects {
      repositories {
          google()
          jcenter()
          flatDir {
              dirs "${project(':unityExport').projectDir}/libs"
                  }
              }
          }
  

• Open <your_flutter_project>/android/settings.gradle and add the following at the end of the file:include ':unityExport'

Run

• Open your main.dart file
• Find and replace the value <YOUR-PROJECT-KEY> with your API key and uncomment the code line
• Find and replace the value <YOUR-ENTRY-ID> with your model's entry ID and uncomment the code line
• Save the file and run the project on an andorid phone
