addTokenTransfer method

Transaction addTokenTransfer(
  1. dynamic to,
  2. int amount,
  3. dynamic tokenAddress, {
  4. int tokenId = 0,
})

Add a token transfer to the transaction @param {String | Uint8List} to Address of the recipient (hexadecimal or binary buffer) @param {int} amount Amount of token to transfer @param {String | Uint8List} tokenAddress Address of token to spend (hexadecimal or binary buffer) @param {int} tokenId ID of the token to use (default to 0)

Implementation

Transaction addTokenTransfer(
  dynamic to,
  int amount,
  dynamic tokenAddress, {
  int tokenId = 0,
}) {
  if (to is! Uint8List && to is! String) {
    throw "'to' must be a string or Uint8List";
  }

  if (to is String) {
    if (!isHex(to)) {
      throw "'to' must be an hexadecimal string";
    }
  } else {
    to = uint8ListToHex(to);
  }

  if (tokenAddress is! Uint8List && tokenAddress is! String) {
    throw "'tokenAddress' must be a string or Uint8List";
  }

  if (tokenAddress is String) {
    if (!isHex(tokenAddress)) {
      throw "'tokenAddress' must be an hexadecimal string";
    }
  } else {
    tokenAddress = uint8ListToHex(tokenAddress);
  }

  if (tokenId.isNaN && tokenId < 0) {
    throw "'tokenId' must be a valid integer >= 0";
  }

  final tokenTransfer = TokenTransfer(
    amount: amount,
    tokenAddress: tokenAddress,
    to: to,
    tokenId: tokenId,
