表格验证和文件上传验证是否分开但在同一方法中使用？

Question

When a form is submitted and it passes its validation which is defined in the ValidateTicketData extends FormRequest-Class you get to a site where there is displayed your form inputs.

There's also an <input type="file" /> to upload a file.
The Validation rules for this is defined in the ValidateUploadedFile extends FormRequest-Class.

When the file passes the validation, there should be displayed something like "file has been uploaded successfully" or so.

Here's the Controller-method:

public function store(ValidateFormData $request, ValidateUploadedFile $requestFile, $param = '')
{
  $validated = $request->validated();
  $formData = $request->all();

  if ($requestFile->hasFile('file')) {
     $file = $requestFile->file('file');
     if ($file->validated()) {
        $filename = uniqid() . $file->getClientOriginalName() . '.' . $file->getClientOriginalExtension();
        $file->storeAs('store', $filename);
        $file->move(public_path('store') . $filename);
     }
  }
  return view('/validation', compact('formData'));
}

I was thinking about something like this.
If I leave out the part of the $requestFile... (so that the Controller would look like this:)

public function store(ValidateFormData $request, $param = '')
{
  $validated = $request->validated();
  $formData = $request->all();

  return view('/validation', compact('formData'));
}

... it works just fine.
The 'validation'-Site is displayed with the validated form inputs.

I somehow think this has something to do with the second Request class $requestFile, but I really don't know how to do it.

Since the file can be validated only after the form data is already validated I need two seperate Request classes..

I hope someone can help me with this.
