Error: type 'int' is not a subtype of type 'BigInt' of 'data' with web3 dart

Question

I am trying to sign a transanction off chain but it's giving me that error.

var data = contract.function('permit').encodeCall([
      credentialsA.address,
      appOwnerCredentials.address,
      1000,

      deadline,
      0,
      Uint8List(32),
      Uint8List(32),
    ]);

the code above is what is generating the error below

E/flutter ( 6175): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: type 'int' is not a subtype of type 'BigInt' of 'data'
E/flutter ( 6175): #0      UintType.encode (package:web3dart/src/contracts/abi/integers.dart)

I am trying to use the "permit" function in erc20 token

Have you used the 'data' variable anywhere?
