flutter-unwrapped will now not come with engine artifacts in its cache directory(`$out/bin/cache`).
To specify a different cache directory, set FLUTTER_CACHE_DIR.
Flutter's wrapper now sets FLUTTER_CACHE_DIR to set engine artifacts.
The sh file `$out/bin/internal/shared.sh` runs when launching Flutter and calls `"$FLUTTER_ROOT/bin/cache/` instead of our environment variable `FLUTTER_CACHE_DIR`.
I decided not to patch it since the script doesn't require engine artifacts(which are the only thing not added by the unwrapped derivation), so it shouldn't fail, and patching it will just be harder to maintain.
Flutter 3.5.0 adds a check to make sure that the Flutter and Dart tool executables are inside the SDK directory.
This does not play nicely with the wrapping and linking techniques used to package it. It is also impossible for there to be an issue related to binary locations, as everything is set up properly in the derivation.
The internal artifacts should be used, as they have been patched to use Nix libraries.
