writeFrom method - RandomAccessFile class - dart:io library (original) (raw)

writeFrom abstract method

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 startand no greater than buffer.length.

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

Implementation

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