Hello @iateadonut
For overriding purpose you can override the route.php.
First you have to make the copy of the file in your package which you want to override then make changes in that file then go to your serviceprovider.php file and write this code in boot() method
$this->publishes([__DIR__ . 'path-where-file-is-located-in-your-package' => 'path-of-file-which- you-want-to-overide' ]);After that you can run php artisan vendor:publish --force and select your package.
This will override the existing file and from that you package controller index will work.
Thank you. Hope this will work for you.
