As to my knowledge it is just warning and not error. It is basically what it's saying, so you have declared variable but you have never used it later in your code. If you are doing lesson 4 you should be using code below as we will be using only 1 variable provided from latestRoundData function. (, int256 answer, , , ) = priceFeed.latestRoundData();
// ETH/USD rate in 18 digit
return uint256(answer * 10000000000); |
