listToString method Null safety
- List list
list to a string by converting each element to a string (by
calling Object.toString), joining them with ", ", and wrapping the
result in "
" and "".
Handles circular references where converting one of the elements
to a string ends up converting
list to a string again.
static String listToString(List list) => IterableBase.iterableToFullString(list, '[', ']');
