readInto method

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

Reads into an existing List<int> from the file. If start is present, the bytes will be filled into buffer from at index start, otherwise index 0. If end is present, the end - start bytes will be read into buffer, otherwise up to buffer.length. If end == start nothing happens.

Returns a Future<int> that completes with the number of bytes read.
