encode static method

String encode(Uint8List bytes)

Takes in a list of bytes converts it to a Uint8List so that one can run bit operations on it, then outputs a base32 String representation.

Implementation

static String encode(Uint8List bytes) {
  int i = 0, index = 0, digit = 0;
  int currByte, nextByte;
  String base32 = '';

  while (i < bytes.length) {
    currByte = bytes[i];

    if (index > 3) {
      if ((i + 1) < bytes.length) {
        nextByte = bytes[i + 1];
      } else {
        nextByte = 0;
      }

      digit = currByte & (0xFF >> index);
      index = (index + 5) % 8;
      digit <<= index;
      digit |= nextByte >> (8 - index);
      i++;
    } else {
      digit = (currByte >> (8 - (index + 5)) & 0x1F);
      index = (index + 5) % 8;
      if (index == 0) {
        i++;
      }
    }
    base32 = base32 + _base32Chars[digit];
  }
  return base32;
}
