Implementation

@override
Uint8List readAtSync(int offset, int length) {
  _checkOpen();
  if (offset < 0 || length < 0 || offset + length > _length) {
    throw RangeError(
      'read [$offset, ${offset + length}) outside 0..$_length',
    );
  }
  return Uint8List.sublistView(_data, offset, offset + length);
}
