Laravel 8：将异常呈现为电子邮件的 html

Question

我将 Laravel 应用升级到最新版本 Laravel 8。我现在的问题是我无法弄清楚如何将应用程序抛出的异常呈现给 html 以便将 html 作为电子邮件发送。

我当前的代码（适用于 Laravel 5）在 App\Exceptions\Handler class:

中呈现和发送异常

public function sendEmail(Exception $exception)
{
    try {
        $e = FlattenException::create($exception);

        $handler = new SymfonyExceptionHandler();

        $html = $handler->getHtml($e);

        $routeName = URL::full();

        Mail::send(new ExceptionEmail($html, $routeName));

    } catch (Exception $ex) {
        if (env("APP_DEBUG") == true) {
            dd($ex);
        }
    }
}

问题是 class \Symfony\Component\Debug\Exception\FlattenException 在我升级后的应用程序中不再存在。

现在在 Laravel 8 中将异常呈现为 html 的合适方法是什么？

非常感谢您。
