Integrate with Flutter Project

Flutter Unity Widget

GitHub - juicycleff/flutter-unity-view-widget: Embeddable unity game engine view for Flutter. Advance demo here https://github.com/juicycleff/flutter-unity-arkit-demoGitHub

This is an open-source project that helps developers to easily integrate Flutter Project with Unity. It includes simple interface to send message to Unity, receive message from Unity, and embed Unity Widget as a component of Flutter Project

Configuration

Following steps are required to embed Unity inside your Flutter project

1. Open the ios/Runner.xcworkspace (workspace, not the project) file in Xcode, right-click on the Navigator (not on an item), go to Add Files to "Runner" and add the ios/UnityLibrary/Unity-Iphone.xcodeproj file.

1. Open the ios/Runner/AppDelegate.swift file and change the following:

     import UIKit
     import Flutter
+    import flutter_unity_widget

     @UIApplicationMain
     @objc class AppDelegate: FlutterAppDelegate {
         override func application(
             _ application: UIApplication,
             didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
         ) -> Bool {
+            InitUnityIntegrationWithOptions(argc: CommandLine.argc, argv: CommandLine.unsafeArgv, launchOptions)

             GeneratedPluginRegistrant.register(with: self)
             return super.application(application, didFinishLaunchingWithOptions: launchOptions)
         }
     }

1. Add the UnityFramework.framework file as a library to the Runner project
