operator []= method Null safety
inherited
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
@override
void operator []=(int index, E value) {
RangeError.checkValidIndex(index, this);
_table[(_head + index) & (_table.length - 1)] = value;
}
