convert method

@override String convert(Bech32 input, { int maxLength = Bech32Validations.maxInputLength, String encoding = 'bech32', })

Converts input and returns the result of the conversion.

Implementation

@override
String convert(Bech32 input, {int maxLength = Bech32Validations.maxInputLength, String encoding = 'bech32'}) {
  var hrp = input.hrp;
  var data = input.data;

  if (hrp.length + data.length + separator.length + Bech32Validations.checksumLength > maxLength) throw TooLong(hrp.length + data.length + 1 + Bech32Validations.checksumLength);
  if (hrp.isEmpty) throw TooShortHrp();
  if (hasOutOfRangeHrpCharacters(hrp)) throw OutOfRangeHrpCharacters(hrp);
  if (isMixedCase(hrp)) throw MixedCase(hrp);

  hrp = hrp.toLowerCase();
  final checkSummed = data + _createChecksum(hrp, data, encoding: encoding);

  if (hasOutOfBoundsChars(checkSummed)) throw OutOfBoundChars('<unknown>');

  return hrp + separator + checkSummed.map((i) => charset[i]).join();
