[FIXED] When Call contractERC20.transferFrom() get Error: UNEXPECTED_ARGUMENT too many arguments

[faisalramdan17]

Describe the bug A clear and concise description of what the bug is.

When Call contractERC20.transferFrom() get this one :

Error: EthersException: UNEXPECTED_ARGUMENT too many arguments: passed to contract

To Reproduce Steps to reproduce the behavior: I think I already put the true parameters like this one, but still get error :

TransactionResponse  resultTransferAllowance = await contractERC20!.transferFrom(
      transFromAddressCtrl.text,
      transToAddressCtrl.text,
      XConverter.amountToBigInt(transAmountCtrl.text, tokenContract!.decimals!),
    );

Getting My Own Solution

So, I try to check your package sourecode in Github : https://github.com/y-pakorn/flutter_web3/blob/main/lib/src/ethers/utils.dart

Then, I get your wrong code :

So meanwhile, currently waiting for your fixes then I have used this code :

final abi = [
      '''function transferFrom(
        address sender,
        address recipient,
        uint256 amount
    ) external returns (bool)''',
    ];

    String address = tokenContract!.contractAddress;
    Contract contract = Contract(address, abi, provider!.getSigner());

    resultTransferAllowance = await contract.send(
      'transferFrom',
      [
        transFromAddressCtrl.text,
        transToAddressCtrl.text,
        XConverter.amountToBigInt(
            transAmountCtrl.text, tokenContract!.decimals!),
      ],
    );

Expected behavior

I think you only need little bit fixed like :

Replace : contract.send('transfer', [sender, recipient, amount.toString()]);

To be like this : contract.send('transferFrom', [sender, recipient, amount.toString()]);

It is simple, right. Thanks so much for your awesome packages. It's very Helpfully. Because I'm creating Dapp for welcoming Meetaverse Indonesia in my country.

It's ok brother. anyway, is this package already support XRPL ? I want to try Dapp for XRPL. You can check this one : https://xrpl.org/docs.html

Thanks

No, this package only supports Ethereum web3 through Ethers.js.
