join method Null safety

  1. @override
String join(
  1. [String separator = ""]
)

Converts each element to a String and concatenates the strings.

Iterates through elements of this iterable, converts each one to a String by calling Object.toString, and then concatenates the strings, with the separator string interleaved between the elements.

Implementation

@override
String join([String separator = ""]) => _values.join(separator);
