toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  final Uint8List chars = Uint8List(_length);
  int charIndex = 0;

  final int fullBytes = _length >> 3;
  for (int i = 0; i < fullBytes; i++) {
    final int byte = _buffer[i];
    for (int j = 7; j >= 0; j--) {
      chars[charIndex++] = ((byte >> j) & 1) + 48;
    }
  }

  final int remainingBits = _length & 7;
  if (remainingBits > 0) {
    final int byte = _buffer[fullBytes];
    for (int i = 0; i < remainingBits; i++) {
      chars[charIndex++] = ((byte >> (7 - i)) & 1) + 48;
    }
  }

  return String.fromCharCodes(chars);
}
