operator [] method
- int index
override
The object at the given index
in the list.
The index
must be a valid index of this list,
which means that index
must be non-negative and
less than length.
Implementation
@override
T operator [](int index) {
var initialIndex = index;
for (var i = 0; i < _lists.length; i++) {
var list = _lists[i];
if (index < list.length) {
return list[index];
}
index -= list.length;
}
throw RangeError.index(initialIndex, this, 'index', null, length);
}
