    You need to pass $product to your controller.

        public function edit(Product $product)
    {
        return view('admin.price.edit', ['product' => $product]));
        // or: return view('admin.price.edit')->with('product', $product);
    }

    Your route needs to pass something to your controller for example your route would look something like:

    Route::get('/products/edit/{product}',[Product::class,'edit']);

    Note that {product} is the product id, you will get it from your url as an example :

    <a href="{{route("products.show",$product->id)}}" class="ml-1 underline">{{$product->name}}</a>

    Then in your controller

    public function edit(Product $product)
{
    return view('admin.price.edit',compact($product));
}
