update the State value in constructor
constructor(
uint256 price,
IERC20 tokenContract,
address buyer,
address seller,
address arbiter,
uint256 arbiterFee
) {
if (address(tokenContract) == address(0)) revert Escrow__TokenZeroAddress();
if (buyer == address(0)) revert Escrow__BuyerZeroAddress();
if (seller == address(0)) revert Escrow__SellerZeroAddress();
if (arbiterFee >= price) revert Escrow__FeeExceedsPrice(price, arbiterFee);
if (tokenContract.balanceOf(address(this)) < price) revert Escrow__MustDeployWithTokenBalance();
i_price = price;
i_tokenContract = tokenContract;
i_buyer = buyer;
i_seller = seller;
i_arbiter = arbiter;
i_arbiterFee = arbiterFee;
++ s_state = State.Created;
