# writeFromSync method

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`.

Throws a FileSystemException if the operation fails.

## Implementation

    void writeFromSync(List<int> buffer, [int start = 0, int end]);
