Filament: Google Maps - Display Locations on Map

We have a simple shop resource to add, edit, and delete shops.

Google Maps API key is set in the .env as GOOGLE_MAPS_API_KEY.

This env is set in the config/services.php.

config/services.php:

'google' => [
    'maps' => [
        'key' => env('GOOGLE_MAPS_API_KEY'),
    ],
],

To show a map, we use a custom page. In the mount() method, we get all the shops, cast them to an array, and assign them to a $shops property.

app/Filament/Pages/Map.php:

use App\Models\Shop;
use Filament\Pages\Page;
use Filament\Support\Icons\Heroicon;
 
class Map extends Page
{
    protected static string | \BackedEnum | null $navigationIcon = Heroicon::OutlinedMapPin;
 
    protected string $view = 'filament.pages.map';
 
    public array $shops = [];
 
    public function mount(): void
    {
        $this->shops = Shop::all(['name', 'lat', 'lng'])->toArray();
    }
}
