failed to load image from storage laravel 8 API in flutter

i'm using laravel 8 & laravel 3.3.1

and i've had problem with my code on flutter right now..

the error is :

════════ Exception caught by image resource service ════════════════════════════

HTTP request failed, statusCode: 404, https://urlAPI/storage/products/1663071858.png ════════════════════════════════════════════════════════════════

and this is my Controller.php

use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Support\Facades\Storage;
use Illuminate\Support\Facades\URL;

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function saveImage($image, $path = 'public')
    {
        if(!$image)
        {
            return null;
        }

        $filename = time().'.png';
        Storage::disk($path)->put($filename, base64_decode($image));

        return URL::to('/').'/storage/'.$path.'/'.$filename;
    }
}

and this my ProductController.php

use Illuminate\Http\Request;
use App\Models\User;
use App\Models\Product;

class ProductController extends Controller
{
    /**

    public function index()
    {
        return response([
            'product' => Product::orderBy('created_at', 'desc')->with('user:id,name,image')->withCount('comments', 'likes')
            ->with('likes', function($like){
                return $like->where('user_id', auth()->user()->id)->select('id', 'user_id', 'product_id')->get();
            })
            ->get()
        ], 200);
    }

    public function store(Request $request)
    {
        $attrs = $request->validate([
            'name'          => 'required|string',
            'price'         => 'required|string',

            'description'   => 'required|string',
            'type'          => 'required|string'
        ]);

        $image = $this->saveImage($request->image, 'products');

        $product = Product::create([
            'user_id'       => auth()->user()->id,
            'name'          => $attrs['name'],

            'image'         => $image
        ]);

        return response([
            'message' => 'Product created.',
            'product' => $product
        ], 200);
    }

    /**

            'product' => Product::where('id', $id)->withCount('comments', 'likes')->get()
        ], 200);
    }
}
