Code

function menu_test_theme_callback($argument) {

  // Test using the variable administrative theme.
  if ($argument == 'use-admin-theme') {
    return config('system.theme')
      ->get('admin');
  }
  elseif ($argument == 'use-stark-theme') {
    return 'stark';
  }
  elseif ($argument == 'use-fake-theme') {
    return 'fake_theme';
