This uses `dart pub deps` (https://dart.dev/tools/pub/cmd/pub-deps) to retrieve information about project dependencies.
It requires a fetch-dart-deps derivation as input.
88275ca6d6 inadvertently stopped the pubspec.lock from changing, as it copied the file before running pub get.
pub get can modify the pubspec.lock to update it to newer formats (for example by adding hashes and updating URLs, see an example diff below). We do not need the modifications at any later stage, so we can preserve the original file.
