Update your AppServiceProvider by adding a view composer to the boot method and using '*' to share it with all views:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;    

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        view()->composer('*', function($view){
            $view_name = str_replace('.', '-', $view->getName());
            view()->share('view_name', $view_name);
        });

    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

{{$view_name}} will be made available to your blade templates.
