:method:`Symfony\\Component\\Routing\\Router::getRouteCollection` method because
that regenerates the routing cache and slows down the application.

Instead, try to generate the URL and catch the
:class:`Symfony\\Component\\Routing\\Exception\\RouteNotFoundException` thrown
when the route doesn't exist::
Instead, use the :method:`Symfony\\Component\\Routing\\Matcher\\Dumper\\CompiledUrlMatcherDumper::getCompiledRoutes`
method to get the list of all the application routes in a performant data format::

use Symfony\Component\Routing\Exception\RouteNotFoundException;
use Symfony\Component\Routing\Matcher\Dumper\CompiledUrlMatcherDumper;

// ...
// if you are checking lots of routes, export this variable into a PHP file to cache it
$compiledRoutes = (new CompiledUrlMatcherDumper($routes))->getCompiledRoutes();

try {
$url = $generator->generate($dynamicRouteName, $parameters);
} catch (RouteNotFoundException $e) {
// the route is not defined...
if (\in_array($routeName, $compiledRoutes, true)) {
// the route exists in the application
}

.. versionadded:: 4.3

The :class:`Symfony\\Component\\Routing\\Matcher\\Dumper\\CompiledUrlMatcherDumper`
class was introduced in Symfony 4.3.
