| * @assertion void writeAsBytesSync( |
| * List<int> bytes, { |
| * FileMode mode: FileMode.write, |
| * bool flush: false |
| * }) |
| * Synchronously write a list of bytes to a file. |
| * |
| * Opens the file, writes the list of bytes to it and closes the file. |
| * |
| * By default writeAsBytesSync creates the file for writing and truncates the |
| * file if it already exists. In order to append the bytes to an existing file, |
| * pass FileMode.append as the optional mode parameter. |
| * |
| * If the flush argument is set to true data written will be flushed to the file |
| * system before returning. |
| * |
| * Throws a FileSystemException if the operation fails. |
| * @description Checks that by default writeAsBytesSync creates the file for |
| * writing and truncates the file if it already exists |
