TON Dart

Ton Dart is a versatile package tailored for seamless integration with TonApi and TonCenter RPC APIs. It empowers developers to effortlessly create, sign, and dispatch transactions while offering robust support for Boc Serialization.

Designed to streamline interactions with Ton wallets such as Basic wallets 1 to 4, Highload Wallet V3, and Jetton Wallet, Ton Dart ensures smooth communication and transaction management within the Ton network.

With Ton Dart, you can harness advanced cryptographic capabilities for secure transaction signing and verification, enhancing the integrity of your operations. Whether you're executing runtime calls or querying accounts, TonDart provides a comprehensive toolkit to handle various data formats and cryptographic operations effectively.

To leverage Ton Dart's capabilities optimally, familiarity with TonApi and TonCenter RPC APIs is recommended. Ton Dart simplifies complex tasks, making it an indispensable tool for developers navigating the Ton ecosystem.

Transfer TON

• transfer

    /// Initialize TonProvider with HTTPProvider for Testnet
  final rpc = TonProvider(HTTPProvider(
    tonApiUrl: "https://testnet.tonapi.io",
    tonCenterUrl: "https://testnet.toncenter.com/api/v2/jsonRPC",

  /// Define private key
  final privateKey = TonPrivateKey.fromBytes(List<int>.filled(32, 39));

  /// Create WalletV4 instance
  final wallet = WalletV4(
    workChain: -1,
    publicKey: privateKey.toPublicKey().toBytes(),
  );

  /// Define destination address
  final destination =
      TonAddress("Ef_GHcGwnw-bASoxTGQRMNwMQ6w9iCQnTqrv1REDfJ5fCYD2");

  /// Construct transfer message and send to the network
  await wallet.sendTransfer(

        destination: destination,
      )
    ],
    privateKey: privateKey,
    rpc: rpc,
  );

• Deploy Jetton minter and mint token

  /// Define owner wallet with WalletV4
  final ownerWallet = WalletV4(
    workChain: -1,
    publicKey: privateKey.toPublicKey().toBytes(),
  );

  /// Create JettonMinter with owner and content

  /// Deploy JettonMinter contract (TOKEN)
  await minter.deploy(
    ownerPrivateKey: privateKey,
    rpc: rpc,
    amount: TonHelper.toNano("0.5"),
  );

  await Future.delayed(const Duration(seconds: 5));

  /// Define the address to which tokens will be minted
  final addressToMint =
      TonAddress("Ef__48F3wya3lEgIHRtpK8jPzYpQCIrfwZfFSEFmjaPQfC56");

  /// Define amounts
  final amount = TonHelper.toNano("0.5");
  final forwardAmount = TonHelper.toNano("0.3");
  final totalAmount = TonHelper.toNano("0.4");
  final jettonAmountForMint = BigInt.parse("1${"0" * 15}");

  /// Mint tokens
  await minter.mint(
    privateKey: privateKey,
    rpc: rpc,
    jettonAmout: jettonAmountForMint,
    forwardTonAmount: forwardAmount,
    totalTonAmount: totalAmount,
    amount: amount + totalAmount,
    to: addressToMint,
  );

• Transfer jetton

   /// Create JettonMinter to query jetton wallet address
  final minter = JettonMinter(
      owner: ownerWallet,
      address: TonAddress("Ef8ns7A4eSwJC1mJf72JDE9byKY9n_xxb1hhloly9heQi_rY"));

  /// Get the address of the Jetton Wallet
  final jettonWalletAddress = await minter.getWalletAddress(
    rpc: rpc,
    owner: ownerWallet.address,
  );

  /// Create JettonWallet instance from the address
  final jettonWallet = JettonWallet.fromAddress(
    jettonWalletAddress: jettonWalletAddress,
    owner: ownerWallet,
  );

  /// Get the balance of the Jetton Wallet
  final balance = await jettonWallet.getBalance(rpc);

  /// Define amounts
  final forwardTonAmount = TonHelper.toNano("0.1");
  final transferAmount = BigInt.from(1000000000);
  final BigInt amount = TonHelper.toNano("0.3");

  /// Transfer tokens from Jetton Wallet
  await jettonWallet.transfer(
    privateKey: privateKey,
    rpc: rpc,
    destination: destination,
    forwardTonAmount: forwardTonAmount,
    jettonAmount: transferAmount,
    amount: amount + forwardTonAmount,
  );
