Q: why does command.execute not work with stdin.readLineSync() in loop ?

Hi, I think I am missing a concept of two here. works functions works as expected, same thing does not work in a loop.

works() {
  // this works as expected.
  final command = RxCommand.createSync<String, String>((s) => s);
  command.listen((s) => print("out-> $s"));
  final inp = stdin.readLineSync();
  command.execute(inp);
}

doesNotWork() {
  // Same this does not work in a loop.
  final command = RxCommand.createSync<String, String>((s) => s);
  command.listen((s) => print("out-> $s"));
  while (true) {
    final inp = stdin.readLineSync();
    command.execute(inp);
  }
}

I'm not sure but I suspect it is because Dart is singlethreaded. try to ass an await Future.Delayed in your loop and see if it works then.
