@override Future<bool> approvedHashes({ required EthereumProvider provider, required ETHAddress address, required List<int> messageHash, })

"stateMutability": "view", Returns a non-zero value if the messageHash is approved by the owner

Implementation

@override
Future<bool> approvedHashes({
  required EthereumProvider provider,
  required ETHAddress address,
  required List<int> messageHash,
}) async {
  final params = [address, messageHash];
  return queryContract<bool>(
    functionName: SafeContractFunction.approvedHashes,
    params: params,
    provider: provider,
    onResponse: (result) {
      final BigInt approved = JsonParser.valueAsBigInt(
        result.elementAtOrNull(0),
      );
      return approved > BigInt.zero;
    },
  );
