Laravel routing without appending any prefix

anybody could help me to solve this issue.. i am very new to laravel.

i have a path in laravel it is like

subdomain.mydomain.com/admin/login

I am trying to call

subdomain.mydomain.com and need to get the login page straight.

Currently its not working

This is the function i am using in routerserviceprovider.php

    protected function mapAdminRoutes()
{
    Route::middleware('subdomain.mydomain.com')
         ->prefix('admin')
        ->namespace($this->namespace)
         ->group(base_path('routes/admin.php'));
}

and in admin.php there is a resource group shows like this

    Route::group(['prefix' => 'admin', 'namespace' => 'Admin'], function() {

    //Login Routes...

  Route::view('login','admin.login');
});

can anyone help with this?
