How do I safely change the "lib" directory name in Flutter Android Studio project?

Question

I've created a Flutter app in Android Studio and I want to change the name of the "lib" directory (in which Dart source files reside) to "src".

However when I do that, the import to 'package:/main.dart' fails. How can I change that?

I changed the path in the .iml file, and the project compiles and runs, but this test file still shows an error.

This name is hardcoded and there is no way to change it.
The whole pub package system depends on that directory name.

There is also a convention that tools like the analyzer support code in lib/src being considered package-private when not exported by files in other directories in lib/.
