 /// - Use the [Uri] class for paths that may have the `file`, `dart` or

 /// - Use [String]s for all filenames and paths that have no scheme prefix.
 /// - Never translate a `dart:` or `package:` URI into a `file:` URI, instead
 ///   translate it to a [String] if the file system path is needed.
 /// - Only use [File] from dart:io at the last moment when it is needed.
