That would be great. People sometimes add string functions as they have 
time, but as far as I know there's no unified plan for this.

How about this?

String pad(String s, char c, int w) {
  if (s.length < w)
    return s + new String(new char[w - s.length()].fill(int i => c));
  else
    return s;
}
