readContract static method

Future readContract(
  1. String address,
  2. String contractAddress,
  3. String methodName,
  4. List<Object> parameters,
  5. String abiJsonString,
)

Read contract

address is public address

contractAddress is contract address

methodName is a contract method name, such as 'mint', 'balanceOf'

parameters is parameters required by the method

abiJsonString is abi json string, such as "[{"inputs":{\"internalType\":\"uint256\",\"name\":\"quantity\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"amount\",\"type\":\"uint256\"},"name":"mint","outputs":[],"stateMutability":"nonpayable","type":"function"}]"

Implementation

static Future<dynamic> readContract(String address, String contractAddress,
    String methodName, List<Object> parameters, String abiJsonString) async {
  final data = await EvmService.customMethod(
      contractAddress, methodName, parameters, abiJsonString);

  final req = RequestBodyEntity();
  req.chainId = await ParticleAuth.getChainId();
  const method = "eth_call";
  final params = [
    {"to": contractAddress, "data": data, "from": address},
    "latest"
  ];

  final result = await EvmService.rpc(method, params);
  return result;
}
