Flutter create not adding build.gradle

If I run

flutter create testapp

followed by

flutter create .

it creates the android directory, however it’s missing key files. (I’m on a windows environment)

android\build.gradle
android\settings.gradle
android\app\build.gradle

and possibly others I’ve yet to discover.

I’m running the master version Flutter version 3.28.0-2.0.pre.38754 (the latest stable version as I write is pending a hotfix that I need).

I’m new to this environment. I’ve tried creating the files manually but run into various problems. When i try to run the default app in android studio, I get

“Error: [!] Your app is using an unsupported Gradle project. To fix this problem, create a new project by running flutter create -t app <app-directory> and then move the dart code, assets and pubspec.yaml to the new project.”

I think I need to sort out the original problem of why the build.gradle files are not being created.

Can anyone tell me why they aren’t being created?
