* @assertion void writeFromSync(List<int> buffer, [int start = 0, int end])
* Synchronously writes from a List<int> to the file. It will read the buffer
* from index start to index end. If start is omitted, it'll start from index 0.
* If end is omitted, it will write to the end of buffer.
*
* @description Checks that method writeFromSync synchronously writes from a
* List<int> to file from index start to index end and if end is omitted, it
* writes to end of buffer.
