operator []= method
Sets the value at the given index
in the list to value
.
The index
must be a valid index of this list,
which means that index
must be non-negative and
less than length.
Implementation

void operator []=(int index, value) {
if (_list.length == index) {
_list.add(value);
} else {
_list[index] = value;
}
}
