operator []= method Null safety

  1. @override
void operator []=(
  1. int index,
  2. E value
)
override

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) {
  if (source.length != _initialSize) {
    throw ConcurrentModificationError(source);
  }
  RangeError.checkValidIndex(index, this, null, length);
  source[start + index] = value;
}
