solidity contract transfer all ether

To transfer all the ether in a Solidity contract, you can use the address type's transfer function. Here's an example of how you can implement it:

pragma solidity ^0.8.0;

contract EtherTransfer {
    function transferAll(address payable recipient) external {

In this example, the transferAll function takes an address payable parameter recipient, which represents the address to which you want to transfer all the ether. The transfer function is then called on recipient with the address(this).balance as the amount to be transferred. address(this).balance retrieves the balance of the current contract.

Keep in mind that when using the transfer function, the recipient contract or address must have a fallback function defined to receive the transferred ether. Otherwise, the transfer will fail.
