encode static method

List<int> encode(String value, { StringEncoding type = StringEncoding.utf8, bool validateB64Padding = true, bool allowUrlSafe = true, Base58Alphabets base58alphabets = Base58Alphabets.bitcoin, })

Encodes the given value string into a list of bytes using the specified type.

The type parameter determines the encoding type to use, with UTF-8 being the default. Returns a list of bytes representing the encoded string.

Implementation

static List<int> encode(String value,
    {StringEncoding type = StringEncoding.utf8,
    bool validateB64Padding = true,
    bool allowUrlSafe = true,
    Base58Alphabets base58alphabets = Base58Alphabets.bitcoin}) {
  try {
    switch (type) {
      case StringEncoding.utf8:
        return utf8.encode(value);
      case StringEncoding.base64:
      case StringEncoding.base64UrlSafe:
        return B64Decoder.decode(value,
            validatePadding: validateB64Padding, urlSafe: allowUrlSafe);
      case StringEncoding.base58:
        return Base58Decoder.decode(value, base58alphabets);
      case StringEncoding.base58Check:
        return Base58Decoder.checkDecode(value, base58alphabets);
      case StringEncoding.hex:
        return BytesUtils.fromHexString(value);
      case StringEncoding.ascii:
        return ascii.encode(value);
    }
  } catch (e) {
    throw ArgumentException("Failed to convert string as ${type.name} bytes.",
        details: {"error": e.toString()});
  }
