Can you experiment with the buildType attributes in you build.gradle files? This should be placed inside the android { } element.

android/app/build.gradle should have a signingConfig defined. This is probably already (partially) there.

buildTypes {
        release {
            // .release if you have a keystore setup
            signingConfig signingConfigs.debug
        }
        debug {
            signingConfig signingConfigs.debug
        }
        profile {
            signingConfig signingConfigs.debug
        }
        innerTest {
            matchingFallbacks = ['debug', 'release']
        }
   }

Sometimes you need to add matching elements to the unity gradle AFTER an export from Unity. https://github.com/juicycleff/flutter-unity-view-widget/issues/527#issuecomment-1028858458 android/unityLibrary/build.gradle

buildTypes {
        release {
        }
        debug {
        }
        profile {
        }
        innerTest {
            matchingFallbacks = ['debug', 'release']
        }
    }

Profile and innerTest can likely be omitted in both if you don't use them.

I tried replacing that in the app level build.gradle but did not work.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Could not resolve all task dependencies for configuration ':app:debugCompileClasspath'.
   > Could not resolve project :unityLibrary.
     Required by:

The consumer was configured to find an API of a component, preferably optimized for Android, as well as attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug', attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm' but:
          - None of the consumable configurations have attributes.

        profile {

        }
   }

Sometimes you need to add matching elements to the unity gradle AFTER an export from Unity. #527 (comment) android/unityLibrary/build.gradle

buildTypes {
        release {
        }
        debug {
        }
        profile {
        }
        innerTest {
            matchingFallbacks = ['debug', 'release']
        }
    }

Profile and innerTest can likely be omitted in both if you don't use them.

If need to support profile mode, also add the above buildTypes to 'android/unityLibrary/xrmanifest.androidlib/build.gradle'

buildTypes { release { } debug { } profile { } innerTest { matchingFallbacks = ['debug', 'release'] } }

Sometimes, check if you have created the folder but hasn't exported from unity, to me it was that.
