nftSymbol = "SYN";

string calldata _uri) external onlyOwner {
super._mint(_to, _tokenId);
super._setTokenUri(_tokenId, _uri);
}

}

@treeder wdyt? The downside is that it requires you to build a list of dependencies and explicitly mention all of them in the header (in theory we could scan every file for imports and try to resolve them)

[treeder]

Why can't we just let solc handle it?

[r-gochain]

@treeder because solc doesn't support that (only remix - they recommend using it) check this thread - https://github.com/gochain/web3/issues/233#issuecomment-1002952217
