inherited
fold<T>(T initialValue, T combine(T previousValue, String element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<String> other) → Iterable<String>

inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
reduce(String combine(String value, String element)) → String
