Answer 1

StreamSplitter.split() from the async can be used for this use case

import 'package:async/async.dart';
...

main() {
  var process = Process.start(...);
  var stdout = StreamSplitter>(process.stdout);
  readStdoutFoo(stdout.split());
  readStdoutBar(stdout.split());
}

readStdoutFoo(Stream> stdout) {
  stdout.transform(utf8.decoder)...
}

readStdoutBar(Stream> stdout) {
  stdout.transform(utf8.decoder)...
}
