Instructions: copy this code to app\Http\Middleware\CustomGoogleTagManagerMiddleware.php and replace \Spatie\GoogleTagManager\GoogleTagManagerMiddleware with \App\Http\Middleware\CustomGoogleTagManagerMiddleware::class in app\Http\Kernel.php.

Now you can flash multiple events to the next request like GoogleTagManager::flash([['event' => 'event1'], ['event' => 'event2'], ['event' => 'event3']]); which will generate something like:

<html>
  <head>
    <script>
        dataLayer.push({
            'event' => 'event1'
        });
        dataLayer.push({
            'event' => 'event2'
        });
        dataLayer.push({
            'event' => 'event3'
        });
    </script>
    <script>/* Google Tag Manager's script */</script>
    <!-- ... -->
  </head>
  <!-- ... -->
</html>
