extraData set to 0 after token transfer

[akhater]

I am packing some variables in the newly implemented "ExtraData" in 4.1.0 however, upon transferring a token the .extraData is set to 0 and not is carried over

[akhater]

ok it seems like i need to override _extraData function for it to work

if I need the .extraData to be carried as is i wrote my function as

function _extraData(
        address from,
        address to,
        uint24 previousExtraData
    ) internal view override returns (uint24) {
    return previousExtraData;
}

does it look OK?

Yes. That’s how you do it.
