show List Tile after clicking on button flutter

Question

I have an Elevatebutton where I want to do that when I click on it, I can see a listTile displayed and after I click on another button the listTile will disappear. I have the code written like this:

ElevatedButton(
                        onPressed: ( ) {
                          setState(() {
                            ListTile(
                              leading: Icon(Icons.add),
                              title: Text('GFG title',textScaleFactor: 1.5,),
                              trailing: Icon(Icons.done),
                            );
                          });
                        },
                        child: Text('button1'),
                        style: ElevatedButton.styleFrom(shape: StadiumBorder()),
                      ),

but even when I click on the button I do not see the listTile. How do I fix this? Can someone help me?

Try below code:

Decalre bool variable

bool buttonPressed = false;

Your Widget:

Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          buttonPressed
              ? ListTile(
                  leading: Icon(Icons.add),
                  title: Text(
                    'GFG title',
                    textScaleFactor: 1.5,
                  ),
                  trailing: Icon(Icons.done),
                )
              : Container(),
          ElevatedButton(
            child: Text("Show Widget"),
            onPressed: () {
              setState(() {
                buttonPressed = true;
              });
            },
          )
        ],
      ),

How can I get this ethereum to my admin account?

Based on the context of the question (the ETH is paid to the token contract - not to a DEX pair contract), I'm assuming you have a custom buy function.

You can expand this buy function to use the transfer() method of address payable to transfer the just received ETH to your admin address.

pragma solidity ^0.8;

contract MyToken {
    address admin = address(0x123);

    function buy() external payable {
        // transfers the whole ETH `value` sent to the `buy()` function
        // to the `admin` address
        payable(admin).transfer(msg.value);

        // ... rest of your code
    }
}

Contract bytecode is immutable (with some edge case exceptions), so in order to perform the change, you'll need to deploy a new contract - can't expand the already deployed contract.
