Since symfony 2.8 you have to pass a full qualified class name instance as argument when create a form or form builder, it does not take an instance of FormTypeInterface anymore.

see https://github.com/symfony/symfony/blob/2.8/UPGRADE-2.8.md

So you should use $form = $this->createForm(SheetType::class); instead.
