| /** |
| * @assertion IOSink openWrite({ |
| * FileMode mode: FileMode.write, |
| * Encoding encoding: utf8 |
| * }) |
| * Creates a new independent IOSink for the file. The IOSink must be closed when |
| * no longer used, to free system resources. |
| * |
| * An IOSink for a file can be opened in two modes: |
| * |
| * FileMode.write: truncates the file to length zero. |
| * FileMode.append: sets the initial write position to the end of the file. |
| * When writing strings through the returned IOSink the encoding specified using |
| * encoding will be used. The returned IOSink has an encoding property which can |
| * be changed after the IOSink has been created. |
| * @description Checks that if file path is wrong then this operation fails |
