operator [] method

  1. @override
bool operator [](
  1. 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
bool operator [](int index) {
  if (index < 0 || index >= length) {
    throw RangeError(index);
  }

  final slot = index ~/ 30;
  final position = slot * 30;
  final mask = 1 << (index - position);
  return (_list[slot] & mask) != 0;
}
