A problem occurred evaluating project ':flutter_unity_widget'.

[kirya355]

Hello everyone, I have tried more than 5 different solutions and none of them worked.

Here are the steps I did:

1. Added in pubspec.yaml
   flutter_unity_widget: ^0.1.6+5
2. Created unity project in "unity" folder
3. Copied Build.cs and XCodePostBuild.cs to unity//Assets/Scripts/Editor/

Open your unity project in Unity Editor. Now you can export the Unity project with Flutter/Export Android (for Unity versions up to 2019.2), Flutter/Export Android (Unity 2019.3.*) (for Unity versions 2019.3 and up, which uses the new Unity as a Library export format), or Flutter/Export IOS menu.

4. Export unity project for android

5. Wrote a simple script
   `import 'package:flutter/material.dart';
   import 'package:flutter/services.dart';
   import 'package:flutter_unity_widget/flutter_unity_widget.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
@OverRide
_MyAppState createState() => _MyAppState();
}

class _MyAppState extends State {
static final GlobalKey _scaffoldKey =
GlobalKey();
UnityWidgetController _unityWidgetController;
double _sliderValue = 0.0;

@OverRide
void initState() {
super.initState();
}

@OverRide
Widget build(BuildContext context) {
return MaterialApp(
home: UnityDemoScreen(),
);
}
}

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

@OverRide
_UnityDemoScreenState createState() => _UnityDemoScreenState();
}

class _UnityDemoScreenState extends State {
static final GlobalKey _scaffoldKey =
GlobalKey();
UnityWidgetController _unityWidgetController;

Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Test003'),
),
key: _scaffoldKey,
body: SafeArea(
bottom: false,
child: WillPopScope(
// ignore: missing_return
onWillPop: () {},
child: Container(
color: Colors.yellow,
child: UnityWidget(
onUnityViewCreated: onUnityCreated,
),
),
),
),
);
}

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

6)Added in android: settings.gradle
include ':app', ':unity-classes' include ":UnityExport" project(":UnityExport").projectDir = file("./UnityExport")

7. I tried to add the unity-classes.jar as a library
   

But this didn't work

log output
idea.log

8. I tried to add the unity-classes.jar as a module
   

9. Accepted this
   

10. Module added in the main directory so I moved it in Android directory
    
    

11. But after this step, I can't build my app
    
    Button for the build isn't working

Before this step:

How to integrate Unity with flutter?

[Jairolaya12x]

Are u using only unity without Vuforia or ARFoundation?
Because this requires an additional setup.
