How to make multiple validations Requests in Laravel?

Question

Laravel allows you to create Requests to validate fields coming from the front end, but I wanted to make several Requests to validate a giant Request. Is it possible? It’s good practice?

I made Traits so they could register each one.

These are the form fields: As you can see they are divided into array

This is the method in the controller you are receiving:

public function store(DealerRequest $request)
{
    try{

        DB::beginTransaction();
            dd($request->all());
            $dealer = $this->dealer->create($request['dealer']);

            $company = $this->createCompany($dealer, $request);

            $this->createPerson($company, $request);

            $this->createLocation($company, $request);

            $this->createContact($company, $request);

            $this->createContract($company, $request);

        DB::commit();

        event(new Welcome($dealer));
        return redirect()->route('representative.dealers.index');
    }catch (\Exception $e){
        dd($e->getMessage());
        DB::rollBack();
        return redirect()->back()->withInput()->with('error', 'Falha no servidor');
    }
}

This method makes calls to other methods that perform Inserts in the database. My idea was that in each method have a request validating their respective fields.

Example:

public function createCompany(Dealer $dealer, CompanyRequest $request){
    try {
        return $dealer->company()->create($request->input());
    }catch (\Exception $e){
        return $e->getMessage();
    }
}

This is a method that instantiates a request, and how it has others instantiating their respective requests. but when executing I have the following error:

I would like a better solution, or how to solve this problem.

Thank you!!
