-   * Note that this request determines the set of requested analysis roots. The

-   * 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

-   * found or the root of the file system is reached. If such a file is found,
-   * it will be used to resolve package: URI’s within the file.
-   *
-   * Parameters
-   *
-   * included: List<FilePath>
-   *
-   *   A list of the files and directories that should be analyzed.

-   * packageRoots: Map<FilePath, FilePath> (optional)
-   *
-   *   A mapping from source directories to package roots that should override
-   *   the normal package: URI resolution mechanism.
-   *
-   *   If a package root is a directory, then the 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.

-   * file: FilePath

-   *   True if the client is only requesting that the values of the options be

-   *   not require any options or if the values of those options are not known.
-   *
-   * Returns
-   *
-   * initialProblems: List<RefactoringProblem>
-   *
-   *   The initial status of the refactoring, i.e. problems related to the
-   *   context in which the refactoring is requested. The array will be empty
-   *   if there are no known problems.
-   *
-   * optionsProblems: List<RefactoringProblem>
-   *
-   *   The options validation status, i.e. problems in the given options, such

-   *
-   * finalProblems: List<RefactoringProblem>

-   *   creation. The array will be empty if there are no known problems.
-   *
-   * feedback: RefactoringFeedback (optional)
-   *
-   *   Data used to provide feedback to the user. The structure of the data is

-   *   that requires them, or if only validation was requested.
-   *
-   * potentialEdits: List<String> (optional)
-   *
-   *   The ids of source edits that are not known to be valid. An edit is not
-   *   known to be valid if there was insufficient type information for the
-   *   server to be able to determine whether or not the code needs to be
