FAILURE: Build failed with an exception.

What went wrong: Could not determine the dependencies of task ':app:preDebugBuild'. Could not resolve all task dependencies for configuration ':app:debugRuntimeClasspath'. Could not find :arcore_client:. Required by: project :app > project :flutter_unity_widget > project :UnityExport Could not find :unityandroidpermissions:. Required by: project :app > project :flutter_unity_widget > project :UnityExport Could not find :UnityARCore:. Required by: project :app > project :flutter_unity_widget > project :UnityExport

Added modules(all 4 files) Project Structure: Capture

Android/Settings.gradle : Capture1

this is a bit more complicated to be honest, if you never worked with android and gradle before, but basically you have to do this

create a module of everything inside the unityexport/libs folder (the *.aar files), so you have all of them as subfolders including a build.gradle with each of them within the android directory
replace the code-block looking similar to the following one in unityexport/build.gradle: implementation project(':unity-classes') implementation project(':ARPresto') implementation project(':UnityARCore') implementation project(':arcore_client') implementation project(':unityandroidpermissions')

make sure once it is working, you save this file as a copy, as currently it is overwritten everytime you do a new export from unity using the flutter menu, the export kinda does the same, but it wants to include the libs directly (using implementation name) which never worked for me

Thanks!! It Worked!🤩

Firstly, It's really complicated.. I couldn't even keep count of the number of build.gradle files..!!

I already had some implementations in my UnityExport/build.gradle :

implementation(name: 'arcore_client', ext:'aar') implementation(name: 'unityandroidpermissions', ext:'aar') implementation(name: 'UnityARCore', ext:'aar')

And so i thought, It was dealt with... and now it worked as I replaced it. Also ARPresto is somehow not needed now.. didn't have that project or module.

Thanks now that it worked👍

Now, this is how the build.gradle file is..

Successfully created the release build but the app is crashing on startup, checking for the reason..

use --no-shrink when building the app, had the same issue

also in case you upgrade the ar-foundation packages in unity, make sure you always replace the modules inside the grade submodules with the updated aar-files from unityexport/libs

were you ever able to fix this? have the same issue now with latest plugin (2.x), since i started to use gradle 5.6.4 (which has to be used to even be able to compile with arcore using unity2020.2b5+)

If any of you have implemented flutter unity widget with arfoundation then please send me the link of project. The project they include in documentation is really old. Please help me.
