stderr property

  1. @override
Stream<List<int>> stderr

The standard error stream of the process as a Stream.

NOTE: stdin, stdout, and stderr are implemented using pipes between the parent process and the spawned subprocess. These pipes have limited capacity. If the subprocess writes to stderr or stdout in excess of that limit without the output being read, the subprocess blocks waiting for the pipe buffer to accept more data. For example:

import 'dart:io';

main() async {
  var process = await Process.start('cat', ['largefile.txt']);
  // The following await statement will never complete because the
  // subprocess never exits since it is blocked waiting for its
  // stdout to be read.
  await process.stderr.forEach(print);


Stream<List<int>> get stderr =>;
