# writeFromSync abstract method

void writeFromSync(

1. List<int> buffer, [
2. int start = 0,
3. int? end

])

Synchronously writes from a `buffer` to the file.

Will read the buffer from index `start` to index `end`. The `start` must be non-negative and no greater than `buffer`.length. If `end` is omitted, it defaults to `buffer`.length. Otherwise `end` must be no less than `start` and no greater than `buffer`.length.

Throws a FileSystemException if the operation fails.

## Implementation

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