A tactic is to just remove anything from the String which are not part of the number.

void main() {
  print(getCurrencySymbol(r'$40.00'));     // $
  print(getCurrencySymbol(r'45$'));        // $
  print(getCurrencySymbol(r'€65,89'));     // €
  print(getCurrencySymbol(r'100,89 DKK')); // DKK
}

String getCurrencySymbol(String value) =>
    value.replaceAll(RegExp(r'[-.,0-9 ]'), '');
