| /// @assertion Future<FileSystemEntity> delete({bool recursive: false}) |
| /// Deletes this FileSystemEntity. |
| /// |
| /// If the FileSystemEntity is a directory, and if recursive is false, the |
| /// directory must be empty. Otherwise, if recursive is true, the directory and |
| /// all sub-directories and files in the directories are deleted. Links are not |
| /// followed when deleting recursively. Only the link is deleted, not its target. |
| /// |
| /// If recursive is true, the FileSystemEntity is deleted even if the type of the |
| /// FileSystemEntity doesn't match the content of the file system. This behavior |
| /// allows delete to be used to unconditionally delete any file system object. |
| /// |
| /// Returns a Future<FileSystemEntity> that completes with this FileSystemEntity |
| /// when the deletion is done. If the FileSystemEntity cannot be deleted, the |
| /// future completes with an exception. |
