Could not determine the dependencies of task ':flutter_unity_widget:compileProfileAidl'.

Solved by adding

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

into the android part of the unityLibrary project build.gradle.

Maybe this can be added to the post process Unity script
