This adds a --middleware option to filter the route:list output by middleware. This can be a single middleware class name or a middleware group name. Like the other filters, it is a simple string contains check. So partial searches are accepted.

php artisan route:list --middleware=api
php artisan route:list --middleware=ThrottleRequests

Note, to filter by middleware within a middleware group, you need to increase the verbosity with the -vv option - just as you would to output middleware within a middleware group.

php artisan route:list -vv --middleware='App\Http\Middleware\ForcePageCache'
