Sending data to and from FormRequest class in Laravel-CodePudding

I'm trying to pass data (more precisely an object,$product) to and from a FormRequest class, StoreImageRequest. After failing validation, the StoreImageRequest redirects to the image upload view, which depends on the model $product being passed (originally from the controller). As I am not sending any data back to the view, it reads $product as null.

I need the whole object ($product) to pass back to the view. I'm not sure if the model exists in the context of the class, and don't know how I can retrieve it AND pass it on to the redirected view to be used there. Laravel docs point to protected $redirectRoute = 'route_name'; but give no clue on data. I guess I'm trying to achieve something in the fashion of return redirect()->route('images.create')->with(['product' => $product] which works in the controller context.

How can I pass the model again to the view?

StoreImageRequest:

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'picture1' => 'mimes:jpeg,bmp,png,jpg|max:1000',
        'picture2' => 'mimes:jpeg,bmp,png,jpg|max:1000',
        'picture3' => 'mimes:jpeg,bmp,png,jpg|max:1000',
    ];
}

public function messages()
{
    return [
        'picture1.mimes' => "Los formatos de archivos soportados son .jpg, .bmp, .png",
        'picture1.max' => "Peso de imagen maximo 1MB",

        'picture2.mimes' => "Los formatos de archivos soportados son .jpg, .bmp, .png",
        'picture2.max' => "Peso de imagen maximo 1MB",

        'picture3.mimes' => "Los formatos de archivos soportados son .jpg, .bmp, .png",
        'picture3.max' => "Peso de imagen maximo 1MB",
    ];
}

uploadimage.blade.php

    <div  style="margin-top: 50px">
    <h1>Seleccione las imagenes del producto</h1>
    <p> Producto: {{ $product->name }}</p>
    <p> Id: {{ $product->id }}</p>
    <p> Marca: {{ $product->brand }}</p>
    <form id="image_form" action="{{ route('store.images', $product->id) }}" method="post" enctype="multipart/form-data">
        @csrf
        <div >
            <input type="file" name="picture1">
        </div>

        <div >
            <input type="file" name="picture2">
        </div>

        <div >
            <input type="file" name="picture3">
        </div>
        <button  type="submit">Subir imagenes</button>
    </form>

You can define a getRedirectUrl() method in your FormRequest class.

<?php

    /**
     * Get the URL to redirect to on a validation error.
     *
     * @return string
     */
    protected function getRedirectUrl()
    {

        $product_id = $this->route()->parameter('product_id');

        return 'store/' . $product_id . '/images'; // Or whatever your route name is

    }

Found a workaround. If the data comes from a Session beforehand, it is possible to retrieve the session in the context of the FormRequest and reflashing it with:

    /**
 * Get the session associated with the request.
 *
 * @return \Illuminate\Session\Store|null
 */
public function getSession()
{
    return $this->session;
    $this->session()->reflash();

}

After that the session (and object $product within it) will be available for the view to use in the form of

{{ session()->get('product') }}
