How to make route in laravel using GET Page?

Before using laravel, usually I route my page using code like this:

//index.php
$get_page=$_GET['page'];
if (empty($get_page) or $get_page=='dashboard')
{
   include ('content/dashboard.php');   
}elseif ($get_page=='schedule')
{
  include ('content/schedule.php');
}

else{
    include ('404/404.php');
}

Is there anyway that I can route my page like that but in Laravel? I prefer to use format : www.example.com/?page=schedule rather than www.example.com/schedule

Answer

Route::get('/', function (Request $request) {
    if($request->query('page')) {
        $page = $request->query('page');
        return view($page);
    }
});
