How I can get multiple value from requestReadContract function?

[afdaldev]

Describe the bug
I try to read smart contract with requestReadContract,, for single value response is good.. but, for multiple value i just get response 1 value

Expected behavior
my expectation return list of value => [maxCap,lockedPeriod,apy ,rewardPercent,totalStaked]
My ABI:
"name": "pools",
"outputs": [
{"internalType": "uint256", "name": "maxCap", "type": "uint256"},
{"internalType": "uint256", "name": "lockedPeriod", "type": "uint256"},
{"internalType": "uint256", "name": "apy", "type": "uint256"},
{"internalType": "uint256", "name": "rewardPercent", "type": "uint256"},
{"internalType": "uint256", "name": "totalStaked", "type": "uint256"}
],

Actual behavior
I just get single response => result: 10000000000000000000000000 (value of maxCap)

Hello, @afdaldev ! Could you post a reproducible pice of code so I can check?

[afdaldev]

final deployedContract = DeployedContract(
              ContractAbi.fromJson(
                abiCode,
                'ISOMAStaking',
              ),
              EthereumAddress.fromHex(
                '0x89E0633eA38CD3539A69A9f88F410A3133f61cF1',
              ),
            );
            
            final result = await walletConnect.w3mService.requestReadContract(
              deployedContract: deployedContract,
              functionName: 'pools',
              rpcUrl: 'https://data-seed-prebsc-1-s1.binance.org:8545',
              parameters: [
                BigInt.from(0),
              ],
            );

            log.d('$result');

here @quetool ..

and now i using web3dart to ReadContract. because, the return data is List<dynamic>

may you can change return of requestReadContract and requestWriteContract to List<dynamic> like from web3dart

@afdaldev what should be the expected result? Could you provide a working example? using web3dart maybe?

[afdaldev]

@quetool here : Web3Example

i think you just need to change return of requestReadContract to List<dynamic> and return value from Web3dart
Because, i see Here you return result.first

[quetool]

Hello @afdaldev I'll check this ASAP or you can also open a PR for this and I'll review it

[quetool]

Hello @afdaldev! I just pushed a fix, could you check by using

dependencies:
  walletconnect_flutter_v2: ^2.2.2-beta02

If you instead need this fix on web3modal_flutter then for now you can just add this new dependency overrides options as follows:

dependencies:
  web3modal_flutter: ^3.1.2
  
dependency_overrides:
  walletconnect_flutter_v2: ^2.2.2-beta02

[afdaldev]

i have try in : https://github.com/afdaldev/Web3Dart_Example/tree/testing_read_contract_with_web3modal

thanks @quetool
it's working like my expectation.
i will wait for next release version in web3modal_flutter

[quetool]

Hello @afdaldev! Are you ok with the current solution? if you don't get the proper response type you can try w3mService.web3App!.requestWriteContract()

[afdaldev]

sure, this is good solution for me. because, i can get all information from my smart contract

for w3mService.web3App!.requestWriteContract(). i don't get any problem.. i still use this function to write

[quetool]

Sounds good! I'll close this issue for now and I'll let you know then the fix is on web3modal as well. Thanks!
