selenium webdriver – Driver switching from one class to a different

Within the following code, I’m attempting to get my driver from the category A to class B. Class B cannot have a constructor and I attempted making a base class, however both Class A will get driver null or Class B will get driver null.

Can somebody level out what I’m doing mistaken?

Class A :

@Listeners(CustomListener.class)
public class AjoutPanier {
    public WebDriver driver;
    
    @BeforeTest
    public void LaunchWebsite() {
        // Launch Chrome
        System.setProperty("webdriver.chrome.driver", "C:chromedriver.exe");
        driver = new ChromeDriver();
        // Acces Web site
        driver.get("https://pileouface.07zr.lu/fr/house/");
        driver.handle().window().maximize();
        Reporter.log(FormatMessageSucces + " Chrome is Opened");
    }.....}

Class B :

public class CustomListener extends AjoutPanier implements ITestListener{
    
    @Override
    public void onTestFailure(ITestResult end result) {
        // TODO Auto-generated methodology stub
        System.out.println("TestFailure acces");
            File file = ((TakesScreenshot)b.driver).getScreenshotAs(OutputType.FILE);
            File ScreenshotName = new File(".//ScreenShots//check.png");
            System.out.println("Recordsdata achieved");
            attempt {
                System.out.println("attempt");
                FileUtils.copyFile(file, ScreenshotName);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                System.out.println("catch");
                e.printStackTrace();
            }
            Reporter.log("");
            System.out.println("*******Screenshot captured********");
    }
}
