safeToString method

String safeToString (Object object)

Safely convert a value to a String description.

The conversion is guaranteed to not throw, so it won't use the object's toString method.

Implementation 

static String safeToString(Object object) {
  if (object is num || object is bool || null == object) {
    return object.toString();
  }
  if (object is String) {
    return _stringToSafeString(object);
  }
  return _objectToString(object);
}
