length property

  1. @override
int get length
inherited

The number of elements in this Iterable.

Counting all elements may involve iterating through all elements and can therefore be slow. Some iterables have a more efficient way to find the number of elements. These must override the default implementation of length.

Implementation

@override
int get length => _base.length;
  1. @override
set length (int newLength)
inherited

Throws an UnsupportedError; operations that change the length of the list are disallowed.

Implementation

@override
set length(int newLength) => _throw();
