# writeFrom method Null safety

Future<RandomAccessFile> writeFrom (

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

)

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 end of `buffer`.

Returns a `Future<RandomAccessFile>` that completes with this RandomAccessFile when the write completes.

## Implementation

    Future<RandomAccessFile> writeFrom(List<int> buffer,
        [int start = 0, int? end]);
