listToString method
Converts 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.
Implementation
static String listToString(List list) =>
IterableBase.iterableToFullString(list, '[', ']');
