You need to use
input.replaceAll(new RegExp(r"\D"), "");
See the replaceAll method signature: String replaceAll (Pattern from, String replace), from must be a Pattern class instance.
Note that r"\D", a raw string literal, is a more convenient way to define regular expressions, since regular string literals, like "\\D", require double escaping of backslashes that form regex escapes.
