Currently the invocation of flutter pub get accepts a target directory

But in the constructor it requires the command to have a pubspec.yml in the same directory it ran

If not pubspec.yml was found in the current directory (even though there is a valid pubspec in the target) the command fails here

Proposed fixed is to delete the required requiresPubspecYaml function from the command constructor and have a helper function on the runCommand method to check for the pubspec on the target directory if one is provided or in the current working directory and its parent folders if not
