elementAt method
override
Returns the index
th element.
The index
must be non-negative and less than length.
Index zero represents the first element (so iterable.elementAt(0)
is
equivalent to iterable.first
).
May iterate through the elements in iteration order, ignoring the
first index
elements and then returning the next.
Some iterables may have a more efficient way to find the element.
Implementation
TextTrackCue elementAt(int index) => this[index];
