Laravel viewに共通変数を使いたいが中身を画面に応じて変えたい

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\View;

class SampleServiceProvider extends ServiceProvider
{
    /**
     * Register services.
     *
     * @return void
     * 
     */
    public function register()
    {

    }

    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {

        View::composer(['Sample1','Sample2','Sample3'],'App\Http\ViewComposers\SampleComposer');

    }
}

<?php 
namespace App\Http\ViewComposers;

use Illuminate\View\View;

class NamingComposer
{
    // 省略

    public function compose(View $view)
    {

        // 画面に応じて分岐
        switch($view->name()){
            case 'Sample1':
                $view->with('success','サンプル１です');
                break;
            case 'Sample2':
                $view->with('success','サンプル２です');
                break;
            case 'Sample3':
                $view->with('success','サンプル３です');
                break;
            default:
                break;
        }
    }
}
