/**
 * @assertion Future<File> create({bool recursive: false})
 * Create the file. Returns a Future<File> that completes with the file when it
 * has been created.
 *
 * If recursive is false, the default, the file is created only if all
 * directories in the path exist. If recursive is true, all non-existing path
 * components are created.
 *
 * Existing files are left untouched by create. Calling create on an existing
 * file might fail if there are restrictive permissions on the file.
 *
 * Completes the future with a FileSystemException if the operation fails.
 * @description Checks that future is completed with a FileSystemException if
 * the operation fails
