Get Laravel 5 controller name in boot method

I have some theme in laravel that boot via this in my Custom package

 $this->app->makeWith( $themeClass, [ $this->app ] )

How I can get current controller name? I need this for know if this page is post or product and get id this product

in view works fine this code

            $routeArray = app( 'request' )->route()->getAction();
            $controllerAction = class_basename( $routeArray['controller'] );

but in theme not works

Call to a member function getAction() on null

I use laravel 5.6
