flatten / group generated files in android studio flutter project

Question

Coming from PHPStorm the IDE by default folds / collapses similar files to one level.

So for example when I have a file.ts and file.js in the same folder, file.js will be hidden in a dropdown below file.ts because PHPStorm knows its generated and assumes the files are related.

Is there a similiar feature in Android Studio when using Flutter?

I want to group / collapse my .freezed.dart and .g.dart files so they are hidden from the project view but not ignored.
