I want to query public variable names on-chain

[Olanetsoft]

wagmi uses:

const { data: useContractReadData } = useContractRead({
address: AVALANCHE_CONTRACT_ADDRESS,
abi: SendMessageContract.abi,
functionName: "getValue",
watch: true,
});

To read function, but I want to read a public variable in the contract, how can I achieve that?

You can simply put the public variable name into the functionName:

const { data, } = useReadContract({ ..., functionName: 'nameOfTheVairable', args: [], })

Also, you can pass index, key or whatever the map/array variable uses as index to retrieve item in it:

const { data, } = useReadContract({ ..., functionName: 'nameOfTheArrayVairable', args: [1], })
