Counter VS manually tokenID ??

[Irfanahmedkhan]

Hello,

i have 1 question, i saw some sample contracts and they were using the counter for openSea.
why we are not using Counter, why we are writing token ID manually at "sell-NFT" section? how someone will know which TOkenID is next ??

thank you

@Irfanahmedkhan Could you please clarify the context, where are we using it?

@alymurtazamemon ... I didn't use it.. but most of the nftmarket sample contracts are using the counter for ID instead of providing TokenID manually ..
like this :https://github.com/Markkop/nft-marketplace/blob/main/contracts/NFT.sol

so my question was, why we didnt use the counter, i am sure there will be any logic but i didnt get ...

@Irfanahmedkhan Ah! It is the same thing that we are doing here, just Openzeppelin has created a proper setup for it. Just like onlyOwner some contract use their custom made onlyOwner modier but some contracts use Openzeppelin Owner.sol contract for checking the owner. If your basics are clear then you can go to these advance things just to save time.
