ERROR send and transfer are only available for objects of type address payable , not address

Question

function finalizeRequest(uint index) public restricted {
    Request storage request = requests[index];
    
    require(request.approvalCount > (approversCount / 2));
    require(!request.complete);
    
    request.recipient.transfer(request.value);
    request.complete = true;
}

error line ---> request.recipient.transfer(request.value);

can someone help me with this? Thank you.

solidity version I'm using:

pragma solidity >0.4.17 <0.8.0;

Answer 1

You need to mark the request.recipient as payable

payable(request.recipient).transfer(request.value);

From the docs page Solidity v0.8.0 Breaking Changes:

The global variables tx.origin and msg.sender have the type address instead of address payable. One can convert them into address payable by using an explicit conversion, i.e., payable(tx.origin) or payable(msg.sender).

Answer 2

If you are using a complier older than 0.6, you can declare recipient as address payable instead of address. If you are using a compiler more or equal to 0.6, you can use the solution provided by @Petr Hejda.
