   *
   * Note that this request determines the set of requested analysis roots. The actual set of
   * analysis roots at any given time is the intersection of this set with the set of files and
   * directories actually present on the filesystem. When the filesystem changes, the actual set of

   * This means that if the client sets an analysis root before the root becomes visible to server in

   * analyzing it. Similarly, server will stop analyzing files that are removed from the file system
   * but they will remain in the set of requested roots.
   *
   * If an included path represents a file, then server will look in the directory containing the
   * file for a pubspec.yaml file. If none is found, then the parents of the directory will be

   *         analyzer will behave as though the associated source directory in the map contains a
   *         special pubspec.yaml file which resolves any package: URI to the corresponding path
   *         within that package root directory. The effect is the same as specifying the package
   *         root directory as a "--package_root" parameter to the Dart VM when executing any Dart
   *         file inside the source directory. If a package root is a file, then the analyzer will
   *         behave as though that file is a ".packages" file in the source directory. The effect is
   *         the same as specifying the file as a "--packages" parameter to the Dart VM when
   *         executing any Dart file inside the source directory. Files in any directories that are
   *         not overridden by this mapping have their package: URI's resolved using the normal
   *         pubspec.yaml mechanism. If this field is absent, or the empty map is specified, that

   *         debugger frame.
   * @param variables The runtime context variables that are potentially referenced in the code.

   *         runtime types. It does not have to be the full list of expressions requested by the
   *         server, for missing expressions their static types will be used. When this field is
