Describe the bug Tried to build and run the following example code :

import 'package:flutter/material.dart';
import 'package:flutter_unity_widget/flutter_unity_widget.dart';

void main() {
  runApp(
    const MaterialApp(
      home: UnityDemoScreen(),
    ),
  );
}

class UnityDemoScreen extends StatefulWidget {
  const UnityDemoScreen({Key? key}) : super(key: key);

  @override
  State<UnityDemoScreen> createState() => _UnityDemoScreenState();
}

class _UnityDemoScreenState extends State<UnityDemoScreen> {
  static final GlobalKey<ScaffoldState> _scaffoldKey =
      GlobalKey<ScaffoldState>();
  UnityWidgetController? _unityWidgetController;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      key: _scaffoldKey,
      body: SafeArea(
        bottom: false,
        child: WillPopScope(
          onWillPop: () async {
            // Pop the category page if Android back button is pressed.
            return true;
          },
          child: Container(
            color: Colors.yellow,
            child: UnityWidget(
              onUnityCreated: onUnityCreated,
            ),
          ),
        ),
      ),
    );
  }

  // Callback that connects the created controller to the unity controller
  void onUnityCreated(controller) {
    _unityWidgetController = controller;
  }
}

got the following errors :

Swift Compiler Error (Xcode): Value of type 'UnityAppController' has no member 'unityMessageHandler' Swift Compiler Error (Xcode): Value of type 'UnityAppController' has no member 'unitySceneLoadedHandler'

During the Unity export, the plugin's build script will add a few lines to the UnityAppController script generated by Unity.

This error indicates that these additions are missing and weren't generated properly.

Thanks for the information.

  • use the latest unitypackage
  • delete any existing ios/unitylibrary folder
  • In unity make sure your buildtarget is set to ios. This error will show up if you click export ios while the unity buildtarget is not ios.
  • Make an ios export using the Flutter menu in Unity.
