• Make sure that you have the built unity project at the android/UnityExport/lib folder
• Make sure that you replaced the dependencies with the good ones in build.gradle of flutter_unity_widget and at the UnityExport module
• Make sure that you have removed the enableSplit options from build.gradle at UnityExport

If you need additional help, just watch this guide, it should be helpful: https://www.youtube.com/watch?v=exNPmv_7--Q

@jiangheng90 that is correct, you omitted that step

[andreibosco]

Try adding the following lines to the end of android/settings.gradle:

include ":UnityExport"
project(":UnityExport").projectDir = file("./UnityExport")

They exist in the example project settings.gradle file but not when creating from scratch using the unity script.

[ceciliamzayek]

I am having the same error.

When I downloaded the repo and did it within the example folder, it worked. But then I tried to make my own folder and use the package within my project I am getting this error. I' followed the ReadMe and the video. @lorant-csonka-planorama what do you mean by: Make sure that you have the built unity project at the android/UnityExport/lib folder?

The other two points I did for sure.

[juicycleff]

Please follow the tutorial in the readme

I am having this issue in December, 2019. I have followed the tutorial as well as this issue. After adding the following lines to the end of android/settings.gradle:

include ":UnityExport"
project(":UnityExport").projectDir = file("./UnityExport")

I received this error, thus making me to believe that part of the issue had been resolved.

Please review your Gradle project setup in the android/ folder.

Other than the built unity project in android/UnityExport/lib folder as I'm not sure whether to place it there because the tutorial states to do something completely different, I've followed all the steps correctly and have attempted it twice.

The supplied tutorial video is massively outdated and offers completely nothing that could help me.

Adding the following lines to the end of `android/settings.gradle in an attempt to fix the previous error, results in a different error.

@lorant-csonka-planorama could you please supply an up-to-date fix for this issue with flutter_unity_widget: ^0.1.6+5? I am fairly new and can't even get my head wrapped around this completely, let alone solve the problem.

[SachinGanesh]

Make sure that you have added ':unity-classes' to settings.gradle

I have tried this just now, and it still says it can't find unity-classes

I have no clue what could be causing this, as it exists in the project.

[AmbrocioIsaias2808]

So, whats the resolution?, i´m having the same issue and i can´t get a workaround, i have already made this changes, i had watched the video (and i agree with the past comments, the video is outdated) and no luck. Please, if you can update the repo solving this issue and make better video explaining detaily the steps.

[AmbrocioIsaias2808]

And well, i know that i´m doing someting wrong but anyway, opening the android folder generated by flutter in android studio and applying the mention changes (and adding some lines) i overpassed the error and now i have this.

In the alone android project it incounter this errors:

And when i try to run it with flutter it says:

[thomas-stockx]

Hi @AmbrocioIsaias2808,

The error you're seeing is quite self-explanatory. It states "Could not resolve project :unity-classes".
As you can see in your project structure, you have several modules (app, flutter_uity_widget, UnityExport, and VuforiaWrapper), but you do not have the unity-classes module.

You can use Android Studio's "import jar/aar" feature for this. Just point it at the unity-classes jar and it should generate the module for you (and adjust your gradle files).

[AmbrocioIsaias2808]

Oh, ok i see, i have seen my mistake, i finally get it running, thanks a lot.

[luisfmcosta]

Hi.
I'm getting the following error when I try to build the release APK.
When I debug it works fine.

[DanFaceira]

same for me and others, i hope this gets fixed soon, cause right now means i cannot release an app

[burkard]

Any update on the :UnityExport issue?

I'm having the same error as @luisfmcosta and @DanFaceira , only when building the release version... no problem with the debug one...

[luisfmcosta]

For Android, I managed to solve the problem by opening the Android project in Android Studio and then generating the signed APK there. For iOS, following the instructions in #93.

@RK21898 Check the following two issues:

1. As @SachinGanesh suggested, add :unity-classes to settings.gradle in your android directory of the flutter project.
   

2. It's easy to import the unity-classes module to the flutter root project directory rather than the android directory. Check to be sure your imported unity-classes library is in the android directory, and if not move it there and allow android studio to update paths when doing so.

[TinyGiantDigital]

@jbrantl8 adding the :unity-classes definitely helped but i'm still struggling with this too.

I can see the unity-classes module in my android folder but it is still complaining, can you see if anything in this screenshot looks wrong? I'm new to android studio so struggling with the process.

[TinyGiantDigital]

I got to the bottom of this! I had to import the .lib file using: (File → New Module → Import .JAR/.AAR Package) and NOT by right clicking and adding as a module as was shown in the video tutorial.

i had the exact same problem
i fixed it by going into android studio, follow all the instruction on the pub.dev and then add a colon to

"implementation project('unity-classes')"
to make it
"implementation project(':unity-classes')"

and maybe comment out this
"implementation(name: 'unity-classes', ext:'jar')"

[SantosVision]

does anybody have this working on 2022? lol... evrything is outdated and tried everything i saw here... no luck
