Flutter config broken for Gradle 8.1.0

See solution here for fix: https://issuetracker.google.com/issues/277166577

From the issue:

Status: Won't Fix (Intended Behavior)
Thanks for sharing the repro. The issue is in the build script that triggers eager task creation, which breaks AGP task configuration. Please use:

tasks.configureEach {
     if(name.startsWith("connectedNet")) {
        enabled = false
    }
}
instead of tasks.whenTaskAdded (see [Gradle docs](https://docs.gradle.org/current/userguide/task_configuration_avoidance.html#sec:old_vs_new_configuration_api_overview) for more info). After this modification, R8 will fail with missing classes, so please follow instructions at https://developer.android.com/build/releases/past-releases/agp-7-0-0-release-notes#r8-missing-class-warning to fix that.

Sidenote: I'd advise against disabling tasks in this way. If you'd like to disable instrumented tests, see https://github.com/android/gradle-recipes/blob/0db8094e5a1a9661f61958db85380320157f5050/Groovy/disableAndroidTest/app/build.gradle#L15.

Can confirm, builds failing because namespace is not set in this plugin.

When you try and set it manually, it generates the error in the link above.

Was not able to solve.

Any idea when we can expect a bump to AGP 8.0+?

In the mean time you can add this to the end of your build.gradle it will fix the problem for all the packages

subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}

subprojects {
    afterEvaluate { project ->
        if (project.hasProperty('android')) {
            project.android {
                if (namespace == null) {
                    namespace project.group
                }
            }
        }        
    }

}

subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}
