transferFrom method

Future<String> transferFrom(
  1. EthereumAddress sender,
  2. EthereumAddress recipient,
  3. BigInt amount, {
  4. required Credentials credentials,
  5. Transaction? transaction,
})

Moves amount tokens from sender to recipient using the allowance mechanism. amount is then deducted from the caller's allowance. Returns a boolean value indicating whether the operation succeeded. Emits a Transfer event.

The optional transaction parameter can be used to override parameters like the gas price, nonce and max gas. The data and to fields will be set by the contract.

Implementation

Future<String> transferFrom(
    _i1.EthereumAddress sender, _i1.EthereumAddress recipient, BigInt amount,
    {required _i1.Credentials credentials,
    _i1.Transaction? transaction}) async {
  final function = self.abi.functions[5];
  assert(checkSignature(function, '23b872dd'));
  final params = [sender, recipient, amount];
  return write(credentials, transaction, function, params);
}
