# iterableToShortString method Null safety

String iterableToShortString (

1. Iterable iterable,
2. [String leftDelimiter = '(',
3. String rightDelimiter = ')']

)

Convert an `Iterable` to a string like IterableBase.toString.

Allows using other delimiters than '(' and ')'.

Handles circular references where converting one of the elements to a string ends up converting `iterable` to a string again.

## Implementation

    static String iterableToShortString(Iterable iterable,
        [String leftDelimiter = '(', String rightDelimiter = ')']) {
      if (_isToStringVisiting(iterable)) {
        if (leftDelimiter == "(" && rightDelimiter == ")") {
          // Avoid creating a new string in the "common" case.
          return "(...)";
        }
        return "$leftDelimiter...$rightDelimiter";
      }
      List<String> parts = <String>[];
      _toStringVisiting.add(iterable);
      try {
        _iterablePartsToStrings(iterable, parts);
      } finally {
        assert(identical(_toStringVisiting.last, iterable));
        _toStringVisiting.removeLast();
      }
      return (StringBuffer(leftDelimiter)
            ..writeAll(parts, ", ")
            ..write(rightDelimiter))
          .toString();
    }
