Implementation

  }

  final indentLength = ByteData(_serializedIndentLengthSize)
    ..setUint32(0, state.indentLength & 0xffffffff, Endian.host);
  output.add(indentLength.buffer.asUint8List());

  var length = 1 + runbackCount + 1 + _serializedIndentLengthSize;
  for (
    var index = 1;
    index < state.indentLengthStack.length &&
        length < _serializationBufferSize;
    index++
  ) {

    output.addByte(state.indentLengthStack[index] & 0xff);
    length++;
