Paramaters and useContractWrite

[isaac-martin]

Hey everyone - have used ethers in the past and am using this now.
Not sure if this is me being thick, or something not working correctly. I couldn't figure it out from the docs nor looking through the src code.
But how do you pass parameters into a function that you call using useContratctWrite ? I thought it would be on the args argument?

I used to have a mint() fn that just took a value - which worked fine. Have extended this function to take a qty as well and this is where my issue starts. The error i get is Error: invalid BigNumber value (argument="value" .....

TSX code looks like the below - will also put contract abi.

const contract = {...}

  const [{ data: mintData, error: mintError, loading: mintLoading }, mint] = useContractWrite(
  contract
   'mint');
  
  const doMint = () => {
    const mintCost = (mintQty * 0.1).toString()
    const cost = ethers.utils.parseEther(mintCost)


    mint({ args: { value: cost, _qty: mintQty } }
    );
  };
  

 {
    "inputs": [
      {
        "internalType": "uint256",
        "name": "_qty",
        "type": "uint256"
      }
    ],
    "name": "mint",
    "outputs": [],
    "stateMutability": "payable",
    "type": "function"
  },

Ok i got this working - but i think the types are wrong for overrides.
This is the code that works to call the function defined above, having the value not as an arg (per this example #49 (comment)) is what was throwing me - as that used to work when there were no other function arguments required

Kind of looks like the types defined here - need to be [PayableOverrides](https://github.com/ethers-io/ethers.js/blob/master/packages/contracts/src.ts/index.ts#L17)

type Config = {
  args?: any | any[]
  overrides?: PayableOverrides
}

@tmm happy to PR if you want to confirm thats the case - guess we could also add an optional field to the useContractWrite to indicate if its payable or not and adjust the types accordingly?
