How can I retrieve source code of given contract address but Etherscan doesn't have any

Question

I want to deploy UniswapV2Factory on a local network and I found that it needs an address:

constructor(address _feeToSetter) public {
    feeToSetter = _feeToSetter;
}

Then I searched this address on Etherscan but found no source code. does anyone know how to resolve it?

In your case you need to provided an address to the constructor, so you will be able to change the reciever of the fee and an address that can change the fee reciever in the future:

    function setFeeTo(address _feeTo) external {
        require(msg.sender == feeToSetter, 'UniswapV2: FORBIDDEN');
        feeTo = _feeTo;
    }

    function setFeeToSetter(address _feeToSetter) external {
        require(msg.sender == feeToSetter, 'UniswapV2: FORBIDDEN');
        feeToSetter = _feeToSetter;
    }
