phpslim v3，检查是否存在命名路由

Question

如何检查phpslim v3中是否存在命名路由？我似乎无法对不存在的名称进行尝试/捕获，执行仍然存在，但有错误。

try {
    $redirect_to = $this->router->pathFor($dynamic);
}
catch (\Exception $e) {
    $redirect_to = $this->router->pathFor('dashboard');
}

谢谢

try {
    $this->router->getNamedRoute($dynamic);
    echo "Route found.";
} catch (RuntimeException $e) {
    echo "Route not found!";
}
