Classes

Base16Data: Byte data represented by Base-16 (Hex) encoded text. @param value the data bytes
Base58Data: Byte data represented by Base-58 encoded text. @param value the underlying bytes data
BifrostDateTime: Convert Bifrost block time (secondsSinceEpoch in UTC) to DateTime and back.
BifrostDateTimeDecoder
BifrostDateTimeEncoder
ByteListConverter
DateTimeConverter
Latin1Converter
Latin1Data: Byte data represented by Latin-1 encoded text. @param value the data bytes
Latin1NullableConverter
Network
PolyFormatter: POLY-specific currency formatter that expects all currency to be in nanopoly and converts it to poly (1 POLY = 1,000,000,000 nanopoly). Compact formatters replace groups of zeros with quantity abbreviation suffixes (i.e. K=thousond, M=million, B=billion & T=trillion). The simple formatters group zeros into threes. Decimal digits defaults to 6 places. The currency factory method allows complete customization.

generatePubKeyHashAddress(Bip32PublicKey publicKey, NetworkId networkPrefix, String propositionType) → ToplAddress: Generate Hash Address using the Public Key and Network Prefix First parameter is the Base-58 encoded byte list of the public key The second parameter is the prefix of the network where the address will be used Third is the type of proposition used Returns the address and whether or not the operation was successful
getAddressNetwork(String address) → Map<String, dynamic>: Returns the networkPrefix for a valid address Returns {success: boolean, networkPrefix:
hex(int c) → int
isValidHex(String hex) → bool
isValidMetadata(Latin1Data? metadata) → bool: Takes in a Latin1Data and returns whether or not it is a valid data/metadata value Returns a bool about whether or not the argument is valid
isValidNetwork(String networkPrefix) → bool: Validates whether the network passed in is valid
isValidPropositionType(String propositionType) → bool: Validates whether the proposition passed in is valid
parseValue(dynamic amount) → num
toHex(Uint8List bArr) → String
toUnitList(String str) → Uint8List
validateAddressByNetwork(String networkPrefix, String address) → Map<String, dynamic>: Checks if the address is valid by the following 4 steps:
validChecksum(List<int> payload) → bool: Verify that the payload has not been corrupted by checking that the checksum is valid
