solana_kit_address 0.5.0

Core Address extension type, codecs, comparator, and PublicKey type for the Solana Kit Dart SDK.

solana_kit_address

Core Address extension type, codecs, comparator, and PublicKey utilities for the Solana Kit Dart SDK.

Provides the Address extension type for validated base58-encoded Solana addresses, codecs for serializing and deserializing addresses, a comparator for sorting addresses by base58 collation rules, and helpers for converting between public key bytes and addresses.

Installation

dependencies:
  solana_kit_address: ^0.1.0

Usage

import 'package:solana_kit_address/solana_kit_address.dart';

// Create a validated address
final addr = address('11111111111111111111111111111111');

// Check if a string is a valid address
if (isAddress(someString)) {
  // it's valid
}

// Encode/decode addresses
final codec = getAddressCodec();
final bytes = codec.encode(addr);
final decoded = codec.decode(bytes);

// Compare addresses using base58 collation order
final comparator = getAddressComparator();
addresses.sort(comparator);

// Convert between public key bytes and addresses
final publicKeyBytes = getPublicKeyFromAddress(addr);
final addrFromKey = getAddressFromPublicKey(publicKeyBytes);

Key APIs

getAddressEncoder()	Returns an encoder that produces exactly 32 bytes
getAddressDecoder()	Returns a decoder that reads 32 bytes into an Address
getAddressComparator()	Returns a base58 collation-order Comparator<Address>
getAddressFromPublicKey()	Converts 32-byte Ed25519 public key to Address
getPublicKeyFromAddress()	Converts an Address to 32-byte Ed25519 public key
