writeFrom method Null safety

Future<RandomAccessFile> writeFrom(
  1. List<int> buffer,
  2. [int start = 0,
  3. int? end]
)

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.

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]);
