我试图签署一个交易链外，但它给我错误。

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

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

字符串
上面的代码是生成下面的错误的原因

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)

我正在尝试使用erc20令牌中的“permit”函数
