URI of a ERC1155 token

Support
1

I have created a ERC1155 contract and deployed it. (Code Below)

I have used to the setURI function to set the URI contract itself.

What function is used to set the URI of the actual tokens I mint from the contract?

Thank you!

    function mint(address account, uint256 id, uint256 amount, bytes memory data)

        _mintBatch(to, ids, amounts, data);
    }

ERC1155 constructor uses it.

constructor(string memory uri_) {
    _setURI(uri_);
}

As explained in our documentation, our base ERC1155 implementation returns the same URI for all token ids, relying on the {id} substitution mechanism described there.

If you want different URIs for each id, you need to extend the contract using inheritance and add the necessary variables and functions.
