feat(dart): Configure when the module is shown (#2312)

* feat(dart): Configure when the module is shown

This makes it possible to configure when the dart module is shown based
on the contents of a directory. This should make it possible to be a lot
more granular when configuring the module.

* docs(dart): add missing detected files

* removed invalid comment
