Feature request: support dynamic SDK locations

With various version managers like [fvm](https://fvm.app/), [asdf](https://asdf-vm.com/) and [mise](https://mise.jdx.dev/) becoming a lot more prevalent, it would be great if the Flutter and Dart plugins had some support for this. I found [this](https://github.com/flutter/flutter-intellij/issues/6289), and I completely understand that program-specific support is beyond the scope of this project. However, I believe that adding a generic feature that simply allows the plugins to locate their SDKs dynamically using a shell command instead of a hard coded path would solve the issue for all of these programs in one swoop.

Would this be an option?
