| * @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 existing files are left untouched by create |
