I want to create a minting function in my contract that allows me to add metadata to the new token. There seems to have been a function in version 2.x that is exactly what I’m looking for(ERC721MetedaMintable). I want to stick to using the newest version of the contracts but I don’t see a similar public function. There is an internal function \_safeMint in the newer version but I’m not sure if making it public is a good idea? I’m new to using OpenZeppelin.

[ERC721Metadata Mintable](https://docs.openzeppelin.com/contracts/2.x/api/token/erc721#ERC721MetadataMintable-mintWithTokenURI-address-uint256-string-)

```
mintWithTokenURI(address to, uint256 tokenId, string tokenURI) → bool

```

[\_safeMint](https://docs.openzeppelin.com/contracts/4.x/api/token/erc721#ERC721-_safeMint-address-uint256-bytes-)

```
_safeMint(address to, uint256 tokenId, bytes _data)
```

Hello @Los, welcome to the community 🙂 . Feel free to [Introduce yourself here!](https://forum.openzeppelin.com/t/introduce-yourself-here/88/)

It is safe to expose `_safeMint`, just like [the Wizard](https://docs.openzeppelin.com/contracts/4.x/wizard) does:
