Laravel - Routing - Fallback Routes

Using the Route::fallback method, you may define a route that will be executed when no other route matches the incoming request. Typically, unhandled requests will automatically render a "404" page via your application's exception handler. However, since you would typically define the fallback route within your routes/web.php file, all middleware in the web middleware group will apply to the route. You are free to add additional middleware to this route as needed:

Route::fallback(function () {
The fallback route should always be the last route registered by your application.
